The Hydro-Filter is an essential part of your business; the advanced polymer is designed to withstand impacts and high temperatures and allows you to impress your customers by showing them how much dirt is removed – something not possible with opaque filters. The redesigned stainless steel filter protects your vacuum motor from harmful debris and maximizes your machine’s CFM output. Additionally, the screw on lid eliminates broken latches so you can focus on your work, not on repairs.
