CORROSION-RESISTANT EXTERIOR
- Precision fit and superior chemical containment
- Ideal for corrosive and abrasive chemicals
- Removable air motor for easy maintenance
There’s no exposed metals and they can be configured in various materials to meet most abrasion, temperature, and chemical compatibility requirements. Plus they’re dead-head capable and achieve high flow rates while minimizing air consumption and operational noise.
