Fan Filter Units (FFU’s)

No matter the critical environment you need to control, you will appreciate the price, performance, and quiet operation of our motorized fan filter units (FFU). FFU’s deliver clean air through high-efficiency particulate air (HEPA) filters, or ultra-low penetration air (ULPA) filters. Our quiet and efficient motorized filter modules are designed to achieve ISO 4 (Class 10) levels of air cleanliness. Angstrom offers a wide variety of sizes, metal construction, and motor types/voltages to better meet your needs. Whether you are looking for a single FFU with a power cord to make your work area cleaner, or you are looking for a smart, fully automated laminar flow cleanroom, Angstrom has a solution for you.

When you buy a cleanroom from Angstrom, powered by any of our fan filter unit models, we can guarantee the room will meet the level of cleanliness you require from ISO 8 (Class 100,000), to ISO 4 (Class 10). Our modular cleanroom systems offer an exceptional level of performance, in a flexible, competitively priced package.

SPX Filter Modules

The SPX is our standard FFU, offering customers a great combination of price, performance and quiet operation. The SPX is our lowest priced FFU, and can reliably deliver over 700 CFM.

High Horsepower (HP)

If maximizing air flow is what you need, the our SPX-HP fan filter unit is for you. The SPX-HP boasts a maximum air flow of 1,000 CFM. With a powerful ½ 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.
