CleanFlo-4 Fan Filter Module

Here’s a fan filter module designed as a nucleus to create any clean environment. Ideal for use in new clean room installations, upgrades and as a HEPA filtered source for class 100 air in many types of laminar flow systems. The lightweight aluminum construction and low profile design allows for trouble free installation even in areas with limited overhead clearance. The Cleanflo-4 is equipped with a HEPA filter that is 99.99% efficient on particles 0.3 microns & larger, the disposable pre-filter prolongs the life of the HEPA filter and cuts maintenance time and cost by more than half. Its energy efficient motor is one of the best in the industry and offers adjustable air velocity levels via a standard speed control. It’s easy to see why any company can meet federal standard 209E/ISO requirements using Cleanflo-4 modules.
