48" Super Air Knife to Blow, Dry & Cool

Supplier: Compressed Air Australia playlist_addCompare

EXAIR's 48" Super Air Knife provides wide surface coverage, offering an efficient way to clean, dry or cool parts, webs or conveyors. At 80 PSIG, the sound level is extremely quiet at 69 dBA, a noise level 11 times quieter than ordinary blowoffs.

Price Guide (Inc GST): POA

The Super Air Knife directs the compressed airflow to a precise, slotted orifice.  It creates a uniform sheet of air across the entire length that immediately pulls in surrounding room air.  Air amplification ratios (entrained air to compressed air) of 40:1 are produced.  The air saving is 63% when compared to typical blowoffs.

Compressed air inlets are provided on each end and the bottom of the Super Air Knife for easy mounting.  Multiple units can be mounted end to end without dead spots.  An optional universal mounting system provides secure, precise positioning.  Many lengths from 3" to 48" (76mm to 1219mm) are available from stock in aluminium or stainless steel.
