Product Overview
49164395 is the intake air filter element for Ingersoll Rand screw air compressors, manufactured to the Donaldson FPG10 specification.
FPG10 is a two-stage intake filtration system. Air first passes through an integrated tangential pre-cleaner: the tangential inlet spins the airflow at high speed, and centrifugal force drives coarse particles to the housing wall. Roughly 85% of coarse dust is separated before it reaches the primary element and is discharged automatically through the Vacuator dust valve at the base of the housing. Pre-cleaned air then enters the primary element, where cellulose filter media performs fine filtration. The benefit is clearest in dusty environments: the primary element carries only the fine-particle load, so service life stays long even under heavy dust exposure.
Sealing also differs from conventional air filters. FPG uses Donaldson's RadialSeal technology: a one-piece molded polyurethane end cap forms a radial seal directly against the housing outlet tube, eliminating the glued gasket used on older axial elements. Fewer parts mean fewer failure points — gasket aging, detachment, and misalignment are no longer possible with the FPG design, and no tools are required for installation or removal.

Technical Parameters
Filtration Performance
| Parameter | Value / Note |
|---|---|
| Filtration Rating | 5 micron class (primary element) |
| Filtration Efficiency | 99.9% (tested to ISO 5011) |
| Pre-Cleaner Efficiency | Up to 85% coarse dust removal (tangential pre-cleaner stage) |
| Filter Class | Two-stage design: centrifugal pre-cleaning plus cellulose primary element; HVAC classification (EN 779) does not apply |
| Dust Holding Capacity | Approx. 1,200 g |
Why the two-stage design matters: on a single-stage filter, the media must handle both coarse and fine particles, so coarse dust builds up on the surface quickly and restriction rises fast. By shifting the coarse load to the centrifugal pre-cleaner, FPG10 markedly improves the primary element's loading profile — a key reason the design is widely used on construction machinery and generator sets operating in dusty conditions.
Flow and Restriction
| Parameter | Value / Note |
|---|---|
| Rated Airflow | Up to 346 cfm / 9.8 m3/min (air cleaner assembly rating) |
| Face Velocity | Approx. 0.038 m/s |
| Initial Pressure Drop | Approx. 0.5-1.0 kPa (approx. 50-100 mmH2O) |
| Operating Differential | From new-element initial restriction up to the clogging alarm value |
| Alarm / Final Restriction | Per the unit's intake restriction indicator (yellow / red zone) |
| Restriction vs. Energy | Each 1 kPa rise in intake restriction increases unit energy consumption by roughly 1% |
Restriction and energy consumption
Rising intake restriction lowers intake pressure and density, so the unit must work harder to hold its discharge pressure and flow, and specific power rises. Calculated on compression ratio theory at 0.7 MPa discharge and 101.3 kPa atmospheric:
| Intake Restriction | Compression Ratio | Relative Energy Increase |
|---|---|---|
| 0 kPa (new element) | 7.91 | Baseline |
| 2 kPa | 8.07 | +2.0% |
| 4 kPa | 8.24 | +4.1% |
| 6 kPa | 8.41 | +6.3% |
Practical implication: as an element moves from new to heavily clogged (0 to 6 kPa), unit energy consumption climbs by roughly 6%. That ongoing electricity cost normally far exceeds the price of one filter element — which is why the FPG10 housing provides a restriction indicator port, so replacement timing is set by actual restriction rather than calendar estimates.
Dimensions and Installation
| Parameter | Value / Note |
|---|---|
| Dimensions | 208 mm OD x 106 mm ID x 409 mm length |
| Construction | Pleated cylindrical element, two-stage RadialSeal primary element |
| Effective Filter Area | Approx. 4.3 m2 |
| Pleat Count | Approx. 103 pleats |
| Pleat Spacing | Approx. 4.8 mm |
| Mounting Interface | Radial push-in; end cap seals against housing outlet tube |
| Sealing | RadialSeal — one-piece molded polyurethane end cap forms the radial seal, no separate gasket |
| Companion Element | Safety element mounted inside the primary element as backup protection |
Procurement note: when cross-checking replacements, verify all three dimensions — 208 mm OD, 106 mm ID, 409 mm length. The FPG design seals radially; push the element in until the end cap contacts the outlet tube, with no additional gasket. Do not add a gasket — it will break the radial seal fit.
Materials
| Parameter | Value / Note |
|---|---|
| Filter Media | Cellulose paper to FPG10 specification |
| Media Weight | Approx. 130 g/m2 |
| Inner / Outer Support | Galvanized steel perforated support (inner cage and outer screen) |
| End Cap | One-piece molded polyurethane (PU) end cap, encapsulating both media ends and the sealing surface |
| Seal | RadialSeal formed by the polyurethane end cap itself; no separate O-ring or gasket |
| Bonding | Molded integrally with the end cap; no separate adhesive layer |
Design note: a conventional axial element uses a metal end cap, glued gasket, and separate seal ring — three parts, any of which can age and cause bypass. FPG encapsulates the end cap, sealing surface, and media ends in a single polyurethane body, reducing part count and improving seal reliability. This is also what enables tool-free servicing.
Operating Tolerance
| Parameter | Value / Note |
|---|---|
| Operating Temperature | Continuous 83 deg C |
| Relative Humidity | Up to 80% RH, non-condensing |
| Burst Strength | Media burst strength approx. 200-400 kPa (per ISO 2758 paper burst test) |
| Collapse Resistance | Element withstands intake alarm differential without collapse (layer-by-layer support in RadialSeal construction) |
| Special Function | Two-stage filtration (integrated tangential pre-cleaner) plus Vacuator automatic dust valve |
| Housing | FPG housing is molded plastic — corrosion-resistant and vibration-tolerant |
Service Life and Maintenance
| Parameter | Value / Note |
|---|---|
| Service Life | 2,000 hours or 3 months, whichever comes first |
| High-Dust Environments | Follow restriction indicator readings; schedule replacement once restriction enters the yellow zone |
| Storage Shelf Life | Approx. 2-3 years (unopened, dry, ventilated conditions) |

Installation and Maintenance Steps
The FPG design is tool-free; a single service takes about 15 minutes.
Shut down, confirm zero pressure, lock out/tag out. Stop the unit, disconnect main power, and apply lockout/tagout. Criterion: controller shows system pressure at 0.
Open the FPG air cleaner access cover. Release the cover latches — FPG uses two spring latches or a twist-off cover, no tools required. Criterion: latches intact, cover not deformed.
Remove the old element. Grip the polyurethane end cap and pull straight out. Criterion: note that the RadialSeal design has no gasket to peel off. If a leftover gasket is found on the housing outlet tube, a non-original part was previously fitted and must be cleaned out.
Inspect the Vacuator dust valve. Check the rubber duckbill valve at the base of the housing. Criterion: valve opens and closes freely, no caked dust, no blockage. This is the most frequently skipped step in FPG maintenance and the most costly to ignore — a blocked dust valve disables the pre-cleaner stage, shifting the full dust load onto the primary element and sharply shortening its life.
Check the pre-cleaner stage and dust traces inside the housing. Look for dust bypass tracks and abnormal build-up in the pre-cleaner swirl zone. Criterion: no dust tracks on the inner wall; if tracks are present, inspect the sealing surfaces.
Fit the new element. Push 49164395 into the housing until the polyurethane end cap contacts the outlet tube. Criterion: end cap seated against the outlet tube; no gasket is needed or permitted.
Refit the cover and check the restriction indicator. Refit the access cover and secure the latches. Confirm the intake restriction indicator reads in the green zone; if resettable, press to reset and confirm it returns correctly. Criterion: green-zone reading, indicator functioning.
Start up and record. Start the unit, run to operating temperature, then read intake restriction. Criterion: restriction within the new-element baseline range; record date, running hours, and restriction reading.
Installation rule: do not start the unit before the element is seated. If the RadialSeal element is not fully pushed in, air bypasses directly through the gap between end cap and outlet tube — both the pre-cleaner and primary element are effectively bypassed, equivalent to running with no filter at all.
FAQ
What specification is 49164395?
A two-stage RadialSeal primary element built to the Donaldson FPG10 specification. The integrated tangential pre-cleaner removes roughly 85% of coarse dust first; the primary element handles fine filtration.
Is it interchangeable with 49101637?
No. 49101637 is FPG09, with different dimensions and rated airflow. Confirmation is simple: read the specification marking on the end cap of the element currently installed — FPG10 means order this part, FPG09 means order 49101637.
Why does this element have no gasket?
Because it uses RadialSeal radial sealing. The polyurethane end cap itself seals against the housing outlet tube, so no glued gasket or separate seal ring is needed. Fewer parts, fewer failure points, and less chance of incorrect installation.
What does the Vacuator dust valve do?
It is the dust discharge port for the pre-cleaner stage. Coarse dust separated by the swirling airflow falls to the base of the housing and discharges automatically through the Vacuator valve. Once the valve clogs, the pre-cleaner stage stops working entirely and all dust loads the primary element. Inspect it at every element change — this is the key maintenance action for the FPG design.
How often should it be replaced?
The recommended interval is 2,000 hours or 3 months, whichever comes first. For greater accuracy, follow the intake restriction indicator: schedule replacement once restriction enters the yellow zone. In high-dust sites, replace earlier based on indicator readings.
Can the element be blown clean and reused?
No. This is a dry, single-use element. It cannot be washed or reverse-blown with compressed air — reverse blowing damages the media fibers and creates invisible channels that let unfiltered air pass through, which is more dangerous than not changing the element at all.
Can a gasket be added to improve sealing?
No, and it is unnecessary. RadialSeal relies on radial compression of the end cap itself. Adding a gasket pushes the element away from the outlet tube and breaks the seal fit, causing bypass.
The restriction indicator never moves — is that normal?
No. A stuck indicator is a common failure point and can give a "clean" reading even when the element is actually clogged. Press-check its return action at every service; if it has failed, replace the element on a conservative time-based interval until the indicator is repaired.
How does the FPG plastic housing compare with metal housings?
The FPG molded housing is corrosion-resistant, lightweight, and vibration-tolerant, and will not rust in coastal salt-spray or damp environments. Tool-free servicing also speeds up on-site maintenance. This is a key reason the FPG series is widely used on construction machinery and mobile equipment.
How can I be 100% certain this is the right part?
Three steps: (1) read the specification marking on the end cap of the installed element and confirm it is FPG10; (2) measure the old part's outer diameter and length against 208 mm and 409 mm; (3) if the old element has been discarded, provide the model marking on the air cleaner housing and we will cross-reference it against the FPG specification.
Compatible Equipment
This element is supplied to the Donaldson FPG10 specification and fits Ingersoll Rand screw air compressors equipped with an FPG10 air cleaner.
FPG10 is a Donaldson air cleaner assembly specification used by OEMs as a standard intake filtration unit. The key checks are:
| Check Item | Specification |
|---|---|
| Air Cleaner Specification | Donaldson FPG10 (elements interchangeable with the FRG10 series) |
| Air Cleaner Rated Airflow | Up to 346 cfm / 9.8 m3/min |
| Role in Assembly | Primary Element |
| Other Specification in Series | FPG09 — part number 49101637, different dimensions and airflow, not interchangeable |
| Sealing System | RadialSeal (polyurethane end cap radial seal) |
How to confirm fitment
- Preferred: read the specification marking on the installed element's end cap. FPG10 means this part fits; FPG09 means order 49101637.
- Alternative: measure the old part's outer diameter and length against 208 mm x 409 mm.
- Fallback: provide the model marking on the air cleaner housing or a photo of the unit nameplate, and we will cross-reference against the FPG specification.
Note on model coverage
Donaldson FPG10 is a general-purpose air cleaner used by multiple OEMs, so fitment for this element is not limited to one specific model list. The correct basis for judgment is the fact that the air cleaner specification is FPG10, not the unit model itself. If the air cleaner specification is not marked on the unit nameplate, confirm using any of the three methods above.
Related Components
The FPG10 air cleaner is a complete system. Beyond the primary element, seven components are serviced together with this part. Listed below by component, function, and inspection point:
| Component | Function | Inspection Point |
|---|---|---|
| Safety Element | Backup element inside the primary element, protecting downstream components if the primary element is damaged or during change intervals | Typically replaced on the same or alternating interval as the primary; check media for damage |
| Vacuator Dust Valve | Automatic dust discharge port for the pre-cleaner stage, expelling centrifugally separated coarse dust | Check at every element change: valve must open and close freely, no caked dust, no blockage |
| Restriction Indicator | Indicates element clogging level; the authoritative basis for replacement timing | Check needle return action; ensure the connecting line is clear |
| Access Cover and Latches | Tool-free opening and closing structure of the FPG housing | Check latches for cracks and cover for deformation; no air leakage once locked |
| FPG Housing Assembly | Molded plastic housing with tangential inlet and pre-cleaner swirl zone | Check inner wall for dust bypass tracks; check plastic parts for cracks |
| Intake Hose and Clamps | Connects the air cleaner to the unit intake duct | Check for cracks, aging, and looseness — bypass leakage is as harmful as running without a filter |
| Other Primary Elements in Series | FPG09 — part number 49101637 | Different dimensions and airflow; not interchangeable — keep separate in stock |
Companion replacement advice: maintenance value in the FPG10 system centers on whether the pre-cleaner stage is working. When changing the primary element, inspect the Vacuator valve and restriction indicator at the same time. If either small part fails, primary element life drops noticeably — they cost far less than the primary element but determine how long it lasts.
