Halar on fan blades
I would like to know, How I can use the coating of HALAR on the Fan Blades and impellers made of Stainless Steel and Aluminum alloy. The Objective is to use the HALAR or any other suitable coating on the blades/ impellers that can prevent rust which may cause spark while operation in the hazardous area. Looking forward hearing from youMumtaz Anwar

I guess that you could use any fluorocarbon on your fan blades ... my only reservation is that ANY fan should be protected against (abrasion & chemical) attack because any coating will be very thin, won't it? A heavy coating could be made by dipping the wheels/impellers in Plastisol BUT you'd sure have to rebalance the wheels after that ! In all cases may I suggest you use a spark tester to test for coating integrity.
Hope this helps.
