# DRIVE UNITS  STERILE AIR – UIA Models

- Air supply units ensure pressurization and the renewal of sterile air. Easy to install.

- UIA units are constructed of bent steel and coated with high-resistance paint.

- Washable pre-filter with 90% efficiency for particles 5 microns in diameter.

- H14 filter with 99.995% MPPS efficiency and 99.999% efficiency for particles 0.3 microns in diameter, according to D.O.P. and NaCl tests.

- High-capacity (up to 2,225 m³/3 /h) and low-noise motor with variable air speed control, allowing for compensation of H14 filter saturation and adjustment of the required airflow to meet the needs of the space to be protected.

- Prior to installing the pump units, a wall opening with the specified dimensions is required.
