02250145‑731 Air Filter Element | Sullair LS16‑60 LS16‑75 LS20‑100HP Compressor

 

The 02250145‑731 is primary intake air filter element for Sullair LS‑series flooded screw compressors. As the first‑line barrier of whole air compression system, it captures airborne dust, silica sand and workshop particulate contaminants before air enters compressor rotor chamber.

 

Many maintenance teams rely purely on running‑hour counter to schedule replacement. However, cement plants, textile mills, metal‑grinding workshops and coastal humid sites will load contaminants onto filter media far earlier than reference hours. Intake differential‑pressure reading is the most reliable trigger for replacement instead of runtime only.

 

Two common hidden failures are frequently underestimated:

 

1. Filter media fully blocked, raises inlet pressure drop and increases compressor power consumption;

2. Damaged sealing gasket, causing unfiltered dust bypass into compressor even with brand‑new filter element. This invisible leak accelerates rotor abrasion, shortens service life of compressor oil, oil filter and oil‑separator element, bringing expensive overhaul risk.

 

Timely replacement of 02250145‑731 protects your high‑value compressor main‑element and reduces long‑term maintenance expenditure.

 

★Important Note: This is primary intake particle filter for compressor inlet, not fine post‑processing coalescing filter. It handles 5‑15μm airborne solid particles, not sub‑micron oil mist.

                                                                                                                                  

 

Manufacturer Part Number：02250145‑731

Applicable Compressor Models：Sullair LS16‑60, LS16‑75, LS20‑100HP Screw Air Compressor

 

Critical Reminder: Do not confirm fitment only according to part number from third‑party catalogs. Different configuration of LS‑series may adopt different intake filter parts. Please send your compressor name‑plate / serial‑number to our technical team for cross‑verification before ordering, avoid wrong‑part shipment and unexpected production downtime.

 

Reference Service‑Life Guidance

 

•Clean indoor industrial environment：Up to 4000 operating hours (reference only)

•Dusty, grinding, textile or coastal high‑humidity workshop：Shorten replacement cycle to 2000‑2500 hours

•Mandatory replacement when intake differential pressure reaches OEM alarm threshold, regardless of accumulated running‑hours.

 

 

1. Prevent cascading wear for compressor core components

Multi‑layer cellulose‑synthetic blended media intercepts solid particles. Well‑functioning 02250145‑731 stops abrasive dust invading rotor chamber, slowing degradation of lubricant oil, oil filter and oil‑separator element.

2. Low‑restriction pleated media to control energy consumption

Optimized pleat layout expands effective filtering surface area, keeps initial intake pressure drop within OEM‑specified window. Heavily clogged filter creates extra suction resistance, forcing compressor to consume more electricity to maintain rated airflow.

3. Robust sealing structure against bypass leakage

Integrated foam rubber gasket and reinforced metal end‑caps maintain reliable sealing under equipment vibration. Damaged gasket will create invisible bypass gap, which can completely nullify filter protection performance even if filter media looks intact.

4. Durable media for varied industrial ambient

Special resin‑impregnated filter paper improves moisture tolerance, reducing media softening or deformation under high‑humidity workshop condition.

5. Direct drop‑in replacement for Sullair LS‑series

Matching outer dimension, inner diameter and gasket profile for original filter housing, no mechanical modification required during swap‑out.

This 02250145‑731 intake filter serves factories operating Sullair LS‑series screw compressors:

 

•General manufacturing & metal‑processing workshops

•Automotive assembly and painting plants

•Textile mills with fiber‑dust pollution

•Cement and construction supporting compressed‑air station

•Food & beverage processing facilities

 

If you observe rising intake differential‑pressure value, frequent oil contamination or shortened oil‑separator service cycle, inspect your intake filter element as priority maintenance item.

 

 

Safety Reminder: Perform full LOTO lock‑out‑tag‑out procedure before opening filter housing. Shut‑down compressor fully.

 

1. Pre‑installation inspection

Power‑off and depressurize compressor. Open air‑filter housing cover. Clean accumulated dust and debris inside filter housing.

 

★Important: Discard old gasket, always install complete new gasket together with new filter element. Re‑using aged gasket is one major source of dust bypass leakage.

2. Correct installation procedure

Position new 02250145‑731 filter element fully inside housing. Press element gently to ensure rubber gasket sits flat against housing sealing face, no twisting, no gap. Improper seating will cause unfiltered‑air bypass. Close and fasten housing cover.

3. Post‑start‑up observation

Restart compressor, record baseline intake differential‑pressure reading after stable full‑load operation. Keep this value for future comparison.

 

★DO NOT test sealing by blocking compressor air inlet, this operation will generate extreme negative pressure and may damage compressor main‑element.

4. Maintenance reminder

This is disposable cellulose intake filter element. We do NOT recommend compressed‑air blow‑clean for reuse. High‑pressure air will create invisible micro‑tears and enlarge pore size on paper media, resulting in hidden dust bypass risk. When differential‑pressure reaches alarm limit, replace element completely instead of attempting cleaning.

 

 

                                     

 

 

Q1: Can I clean and reuse 02250145‑731 with compressed air to save cost?

A: Not recommended. High‑pressure blowing may remove surface dust, but it creates invisible micro‑cracks on cellulose media. Fine abrasive dust will bypass these micro‑defects and damage your compressor rotor. Paper‑type intake filter is designed for full replacement, not repeated cleaning.

 

Q2: My filter still looks clean, but differential‑pressure alarm pops up, what is the reason?

A: Fine dust can penetrate into depth of pleated media, causing internal clogging while filter surface still looks acceptable. Always follow differential‑pressure value instead of visual appearance only.

 

Q3: Does 02250145‑731 fit all Sullair screw compressors?

A: No. It is dedicated for LS16‑60, LS16‑75, LS20‑100HP series. Other Sullair models adopt different intake filter part‑numbers. Submit your compressor serial‑number and we cross‑check compatibility for you.

 

Q4: What risk will occur if gasket sealing fails even with brand‑new filter?

A: Dust bypass through gasket gap will directly enter compression chamber. It will accelerate rotor wear, degrade compressor oil rapidly, and shorten service life of oil filter and oil‑separator, may lead to expensive main‑element overhaul.

 

Q5: Should I strictly replace filter exactly at 4000 running‑hours?

A: 4000‑hour is reference value under clean ambient. In dusty workshops you must shorten replacement cycle. Intake differential‑pressure alarm threshold takes priority over runtime counter.

 

 

•Pre‑order compatibility verification: Send your compressor serial‑number, our technical team double‑check fitment before shipment to avoid wrong‑part delivery.

•Pre‑shipment visual inspection: Check filter media integrity, end‑cap and gasket condition before packing; inspection video can be provided for bulk orders.

•Flexible global logistics: Urgent express delivery for emergency breakdown maintenance; sea‑freight solution for bulk‑project procurement.

•Spare‑part technical support: If you need full maintenance kit (air filter, oil filter, oil‑separator) for your Sullair LS‑series compressor, share machine name‑plate information and we confirm complete spare‑part list for you.
