Overview
The Piab N750FF is a 3/4″ NPT fine flow POREX muffler engineered for noise reduction in vacuum pump and ejector exhaust applications. Manufactured with a porous polyethylene body, this muffler combines effective acoustic attenuation with minimal backpressure. The FF designation indicates fine flow specification—ideal for systems requiring high filtration and noise suppression without excessive flow restriction.
Key Features
- Fine flow (FF) design with 35-micron porous element for excellent noise attenuation
- High-density porous polyethylene construction for durability and chemical resistance
- 3/4″ NPT male thread connection for standard industrial installations
- Reduces air blast noise at pneumatic valve exhaust ports
- Low pressure drop and minimal maintenance requirements
- Red base color distinguishes fine flow version from standard or coarse variants
