YIDINGAIR FILTRATION
Product overview
What it is and where it fits.
The AR209 protects air compressors and similar intake equipment from dust that would wear internal parts and contaminate compressed air. Two versions are listed: a deep glass-fibre filter for high efficiency at small particle sizes, and a shallow synthetic filter for coarser duty.
The deep version (24 × 24 × 11½ in) uses water-resistant micro-glass fibre, a galvanised frame, epoxy-sealed media ends and a HEPA-grade gasket, with a listed dust capacity of 585 g and pleat strength above 34 in w.g. The shallow version (24 × 24 × 1½ in) uses synthetic media with PVC end seals and protective mesh, rated at least 98% at 10 µm.

Selection guide
How to choose.
Choose by the particle size you must stop
The deep glass-fibre version targets fine particles around 2 µm; the shallow synthetic version targets coarser dust around 10 µm.

Common questions.
Why filter compressor intake air?+
Dust entering a compressor wears valves and rotors and ends up in the compressed air. An intake filter extends equipment life and keeps the downstream air cleaner.
