STjh long 24 x 48 inch standard high-airflow FFU with extended aluminum deck and a central square prefilter

STJH-HIGH-AIRFLOW-FFU-24X48-950CFM

Fan Filter Unit 24 × 48 in High-Airflow

The highest-volume standard high-airflow FFU in this group, rated up to 950 CFM.

200-950 CFM operating range
600 x 1200 mm full-length footprint
650 CFM reference airflow at 90 FPM

Introduction de produit

This full-length 24 x 48 in model provides the largest standard airflow range in the accepted high-flow family, from 200 to 950 CFM. It supplies 650 CFM at a 90 FPM reference point and carries a 66 lb housing across a 600 x 1200 x 364 mm envelope. The model suits broad ceiling zones where one module should cover more area and deliver more volume than the 24 x 36 in format.

Key Features

Maximum standard airflow

The 950 CFM upper limit provides the greatest volume in the non-RSR high-airflow group.

Broad filter-face coverage

A two-by-four-foot cabinet can reduce module count across large production ceiling zones.

Adjustable ECM output

The ECM can be commissioned below maximum duty to match the installed filter and room return system.

Applications

Suitable for high-coverage electronics, pharmaceutical and precision-manufacturing ceilings, especially where the airflow plan favors fewer large modules. The 950 CFM capability must be coordinated with room returns, ceiling support and acceptable sound levels.

Solutions for Your Application

Too many medium FFUs add controls and joints to a large cleanroom ceiling.Use the 2 x 4 ft module to consolidate coverage where the structural grid and air balance permit.

Operating at maximum volume may create more airflow or noise than the process needs.Commission the ECM from the 650 CFM reference duty and increase output only after verifying the room pressure and velocity profile.

Options disponibles

Confirm the final-filter grade, ECM control interface, voltage, housing construction and ceiling support. Select the actual airflow from the measured resistance and cleanliness requirement.
