Maximum air flow, for minimum contaminants.

High Horsepower (HP)

If maximizing air flow is what you need, the Technical Air Products' SPX-HP fan filter unit is for you. The SPX-HP boasts a maximum air flow of 1,000 CFM. With a powerful 1/2 horsepower motor, the SPX-HP FFU has the least amount of CFM drop when used with more efficient filter media. For instance, the SPX-HP still delivers over 900 CFM when used with a high-efficiency ULPA filter.
