How often should you change a construction machine air filter? Stop using the handbook hours
The same excavator can get twice the filter life in a factory yard as in a quarry. The reliable trigger is restriction, not hours. Here is a practical method and a field checklist.

Finer is not automatically better: finer media means higher pressure drop, shorter life and more energy use. The goal is matching filtration rating to the system’s target cleanliness level.

Spotting a counterfeit filter: five checks you can do on the loading dock
A counterfeit can look almost identical. Media, end-cap adhesive and the bypass valve are the hardest things to fake — here are five checks that need no instruments.

All questions01 Are you an authorized FILTERSUN distributor? Are the filters genuine?
Yes. We are an authorized FILTERSUN distributor buying through the manufacturer’s official channel. We can provide authorization documents and batch records for traceability. We do not sell refurbished or grey-market stock — one failed filter that scores a cylinder or sticks a hydraulic valve costs far more than the money saved.
02 I only have a part number. Can you match the filter?
Yes. Send us the part number by WeChat, WhatsApp, email or the enquiry form. We verify dimensions, thread and seal type, then reply with the matching FILTERSUN part number and lead time. If it is not in our 1,500+ item catalogue we check with the factory — we will not substitute a “close enough” number.
03 I do not have a part number, only the machine model.
Yes. Give us the brand and model (e.g. “Komatsu PC200-8”, “CAT 320D”) and we build a complete filter list for that machine: air filter, safety inner element, lube filter, fuel filter with water separator, hydraulic filter, pilot filter and return filter. You can also send a photo of the old filter with its outside dimensions and we will match it manually.
04 What is the minimum order quantity? Can I mix part numbers?
One piece is enough for standard part numbers, and you can mix part numbers in a single order. Volume pricing applies from 50 pieces of one number, or above a single-order threshold. Fleets and resellers can work on an annual framework agreement with monthly settlement.
05 What is the lead time? Do you hold stock?
More than 3,000 fast-moving part numbers are held in stock and ship the same day if the order is confirmed before 16:00 on a working day. Non-stock numbers typically take 2–5 working days from the factory; custom items take 7–15 working days. Tell us at order time if it is urgent and we will prioritise it, with express or air freight if needed.
Send the part number — we handle the rest
