Porous Breather-Vent-Filter
Porous Breather-Vent-Filter
ALWITCO Porous Breather Vent-Filter is a high-durability, low-profile safety component designed for vacuum and pressure equalization in confined pneumatic environments. Manufactured by the Allied Witan Company and supplied by Ardee Hi-Tech Pvt. Ltd., these compact vents serve as an excellent, cost-effective alternative when standard filter-mufflers cannot fit into restricted machine boundaries. These flat-profile units allow unrestricted bi-directional airflow to prevent pressure buildup or vacuum collapse, while acting as a barrier to keep external debris out of internal mechanical chambers.
Ardee Hi-Tech Pvt Ltd. is the official and authorized distributor of ALWITCO products in India.
