Room-side replaceable fan/filter units from Terra

Avoids costly downtime and recertification during filter replacement

Terra’s WhisperFlow room-side replaceable (RSR) fan/filter units (FFUs) enable the replacement of HEPA or ULPA filters inside the cleanroom without having to shut down and breach the cleanroom seal.

The modules are designed to allow easy access to filters while limiting downtime for regular maintenance. Traditional filter units require roof access or a complete shutdown of the cleanroom for filter replacement. Downtime and recertification can be time-consuming and costly.

Terra’s RSR filter modules feature gel-filled channels that seal against the module housing. From inside the room, the easy-open clamps release the filter for service or replacement. Once the new filter is lifted into place, the room is operational.

WhisperFlow fan/filter units operate at a low decibel level, providing a comfortable work environment, the company says. The quarter horsepower direct-drive motor is energy efficient and non-contaminating.

Terra Universal has more than 35 years of experience manufacturing modular cleanrooms and equipment.
