Product Overview
47742049001 is the intake air filter element for the Ingersoll Rand MM350-2S two-stage screw air compressor. It sits inside the external air filter housing, upstream of the airend intake.
External air is drawn through the element first; dust, grit and fibres are trapped on the media surface and in its depth, so only clean air reaches the airend.
One point to check before you buy: the MM350-2S intake system does not use a single filter part number. The air filter configuration varies with machine version and build, so more than one element part number runs in parallel. This page makes no assumption that one element fits every MM350-2S. Always read the part number on the old element and confirm its mounting position — do not order on machine model alone. This is the most common sourcing error on large two-stage compressor consumables.
Duty context: the MM350-2S is a 350 kW two-stage machine with 64.1 m³/min displacement at 8.5 bar(g). It moves a high intake air volume per hour, so element area and structural strength must match that duty.

Technical Parameters
Filtration performance
| Parameter | Value / note |
|---|---|
| Filtration rating | 5–10 μm |
| Filtration efficiency | ≥98% for particles ≥5 μm |
| Filter class | HVAC filter classes (EN 779) do not apply; intake elements are rated to ISO 5011 by efficiency, restriction and dust holding capacity |
Flow and restriction
| Parameter | Value / note |
|---|---|
| Rated air flow | Matched to MM350-2S intake (64.1 m³/min @ 8.5 bar) |
| Initial pressure drop | Approx. 0.5–1.0 kPa (approx. 50–100 mmH₂O) |
| Alarm / final restriction | Per the machine intake restriction indicator or controller vacuum alarm |
| Restriction vs. energy | Each 1 kPa of intake restriction adds roughly 1% to machine energy use |
Rising intake restriction lowers intake pressure and air density. To hold the set discharge pressure and flow, the machine does more work and specific power rises. On a 350 kW machine running 8,000 hours a year, restriction climbing from a new element to a heavily loaded one adds roughly 6% to energy use — far more than the cost of the element. Replace on restriction reading, not on the calendar alone.

On dimensions: this is a newer 11-digit part number, and no reliable published dimensions are available from OEM or third-party sources. To avoid a wrong-size order, this page gives no estimated figures. Measure the old element's outside diameter, mounting bore and overall height, or send photos and measurements for us to cross-check. Other element part numbers for the same machine do not share these dimensions — never carry dimensions across part numbers.
Installation Steps
The external filter housing on a large two-stage machine is sizeable; allow about 30–40 minutes and work with two people.
- Shut down, confirm zero pressure, lock out. Isolate the main power and apply a lockout tag; open the receiver drain valve to vent. Check: controller shows 0 system pressure and no residual air noise.
- Confirm the part number before you touch anything. Check: read the number on the old element and compare digit by digit with the part you bought. Where a model uses more than one intake element number, fitting the wrong one causes a poor seal or prevents seating.
- Open the filter housing. Release the clamps or bolts on the end cover in a diagonal sequence. Check: cover not distorted, clamps not seized. Support large covers before the last fastener is released.
- Remove the old element and inspect it. Withdraw vertically; use a lift aid if heavy. Check: even grey-brown dust is normal; oily residue points to oil carry-over upstream and needs investigation; torn media, loose end caps or a flattened seal mean immediate replacement.
- Clean the housing interior. Wipe the inner walls, base and sealing face with a dry lint-free cloth. Do not blow compressed air into the housing — it drives dust into the intake. Check: no loose dust, sealing face flat with no pits. In humid regions, also check for condensate at the housing base.
- Fit the new element and confirm seating. Compare mounting diameter, overall height and seal type against the old part, then push fully home with the seal face flush and no trapped material. Check: element centred, no tilt, even seal compression all round.
- Refit the cover and tighten. Tighten clamps or bolts evenly in a diagonal sequence. Check: even gap between cover and housing, no skew.
- Start up and verify. Restore power and run 5–10 minutes, then read intake restriction. Check: restriction in the new-element band, no abnormal whistle at the intake (usually a sign of an unseated element or poor seal). Log the date, running hours and restriction reading.
Non-negotiable: never start the machine with the element unseated. Running without an element or with a poor seal sends unfiltered air straight into the two-stage rotor and can cause irreversible wear in a short time.
FAQ
Which machines use 47742049001?
The Ingersoll Rand MM350-2S two-stage screw compressor (350 kW, 8.5 bar(g), 64.1 m³/min).
Is this the only intake filter part number for the MM350-2S?
No. This model uses more than one intake element part number, each with its own mounting position and function. That is why we keep stressing the old-element part number — ordering on machine model alone is the most common mistake on this platform.
How do I confirm which element I need?
Three steps: (1) read the part number on the old element and compare digit by digit; (2) note the element's position on the machine (which stage, which side); (3) if the old part is already discarded, send the machine nameplate and filter housing marking and we will cross-check against the build. Do not judge by appearance alone.
How often should it be changed?
The recommended interval is 2,000 hours or 3 months, whichever comes first. The more accurate method is to watch the intake restriction reading and change when it enters the alarm band. On dusty sites, change earlier based on restriction.
Can I blow it clean and reuse it?
No. This is a dry, single-use element and is not designed to be washed. Blowing with compressed air only removes surface dust; fine particles trapped in the media depth stay put, and the air pressure can tear fibres or distort pleats, creating paths you cannot see. A cleaned element can look fine while no longer filtering — the risk outweighs the saving.
Why is timely replacement so important on this machine?
The MM350-2S is a 350 kW continuous-duty machine. Each 1 kPa of intake restriction adds roughly 1% to energy use; from a new element to a heavily loaded one the rise is about 6%, and at 8,000 hours a year the electricity cost far exceeds a set of elements. Unfiltered air also contaminates the two-stage rotor, the separator element and the lubricant. It is one of the clearest return-on-investment service parts on the machine.
What else should I check during the change?
Intake hose and clamps (cracks, ageing, looseness), housing sealing face, restriction indicator (does the needle return correctly), plus the oil filter and separator element on the same cycle. Bypass leakage is as damaging as running without an element, so the hose check is not optional.
Do you hold stock, and what is the lead time?
Regular stock items ship within 24 hours. Southeast Asia approx. 3–7 days, Middle East approx. 7–10 days, Africa and Latin America approx. 10–18 days, Russia/Belarus approx. 10–15 days. Confirm at the time of enquiry against current stock and sailing schedules.
Are the dimensions listed?
This is a newer 11-digit part number and no reliable published dimensions exist. To avoid a wrong-size order, we do not publish estimates. Measure the old element's outside diameter, mounting bore and overall height before ordering, or contact us for cross-checking help.
Machine Compatibility
This element suits the MM model in the Ingersoll Rand SSR two-stage 350 kW platform.
| No. | Model | Nominal power | Discharge pressure | Displacement | Note |
|---|---|---|---|---|---|
| 1 | MM350-2S | 350 kW | 8.5 bar(g) | 64.1 m³/min | Machine covered by this page |
Other pressure ratings on the same platform (for identification and to rule out mis-purchase):
| Model | Discharge pressure | Displacement | Note |
|---|---|---|---|
| ML350-2S | 7.5 bar(g) | 69.2 m³/min | Same power platform, low-pressure version |
| MH350-2S | 10 bar(g) | 59.5 m³/min | Same power platform, high-pressure version |
| MXU350-2S | 14 bar(g) | 50.2 m³/min | Same power platform, extra-high-pressure version |
This model uses more than one intake filter part number. The MM350-2S air filter uses multiple elements according to build, each with its own part number. This page covers one part number only and makes no compatibility claim for the others. To confirm before ordering:
- Preferred: read the part number on the old element and compare digit by digit.
- Alternative: note the element position (which stage / which side) and send a machine nameplate photo; we will cross-check against the build.
- Fallback: measure the old part's outside diameter, mounting bore and overall height and compare by size.
- This product corresponds to row 1, MM350-2S.
- If your machine is an ML350-2S, MH350-2S or MXU350-2S, send the nameplate model and we will verify the intake element part number separately.
- A matching machine model does not mean a matching element — element part numbers within one model are not interchangeable.
Related Parts
On the MM350-2S intake and lubrication system, the parts below run on the same cycle or should be checked at the same time. For exact part numbers, refer to the machine's parts manual.
| Part | Location | Function | Check point |
|---|---|---|---|
| Other intake elements for this model | Air filter housing | Cover the model's filter build; part numbers differ from this page | Separate by part number in stock and on orders — never assume interchangeability by model |
| Oil filter element | Main oil circuit | Traps wear debris and sludge, protecting the two-stage rotor and bearings | Change on the same cycle as the air filter; check the housing seal face for weeping afterwards |
| Separator element | Oil separator tank | Separates oil mist from compressed air and returns oil, controlling oil carry-over | Check the scavenge line for blockage at the same time (poor return raises oil carry-over directly) |
| Restriction indicator / intake vacuum alarm | Filter housing or controller | Shows element loading and is the authoritative guide to change timing | Check needle return and sensing line; if faulty, revert to a conservative interval |
| Intake hose and clamps | Between filter housing and airend intake | Keeps the intake path leak-free with no unfiltered bypass | Check for cracks, ageing and looseness; bypass leakage is as damaging as no element |
| Housing sealing face and end cover | Air filter housing | Ensures a reliable seal once the element is compressed | Check for pits and corrosion; check the cover for distortion |
| Lubricant | Airend lubrication system | Lubrication and sealing; two-stage machines are demanding on oil quality | Test and change to the machine's schedule; do not mix grades |
Grouping suggestion: on large two-stage machines, schedule the air filter, oil filter and separator element into one shutdown to avoid staggered intervals and repeated downtime. On dusty sites, fit a high-dust pre-cleaner first — pre-cleaners cost far less than the main element and change faster.
