View Model/Dimensions & Sample Drawings

Applications:

Microelectronic Fabrication, Medical Device Manufacturing, QC Inspection, Sterile Filling & Packaging, Pharmaceutical Processing, Semiconductor Manufacturing

Description:

The Fan Filter Unit draws ambient air from above & generates a uni-directional vertical airflow pattern that exits beneath the vinyl curtain. Depending on the quantity of modules used and filter efficiency an ISO 8 Class 100,000 to ISO 4 / Class 10 clean laminar airflow can be established inside the Softwall environment. The FDE Series includes HEPA fan modules, cleanroom tiles, cleanroom light fixtures that provide 125 ft. candle coverage. The standard unit consists of tubular steel with a painted (or Stainless steel) finish, on isolation levelers. A solid clear vinyl curtain spaced above the floor allows a continuous downflow purge of clean air. Various configurations & Cleanroom Classes are available to meet your specific needs.

Construction:

2” or 3” square (tubular – 11 gauge) welded frame – Painted or Stainless Steel with heavy-duty isolation levelers; Standard Inside ceiling is 8 ft. (others are available). Aluminum, gasketed, T-Grid ceiling system with 3/4” angle on perimeter. Pre-assembled at factory for easy installation. Gasketing ensures seal when installed. Solid, clear 40 mil vinyl curtain perimeter with overlapping entrance (or optional Polycarbonate walls).

Electrical & Power Requirements:

All electrical components are UL Approved / NEC compliant. Standard 115V, 15A 1 Ph, 60 Hz., 15 ft. SJO power cord with 3-prong ground plug. 230V also available.

Motor/Blower Assembly:

High efficiency Impellor motors reduce electrical load. Motors are thermally protected & self-lubricating. High capacity metal backward curved impellers within direct drive external rotor motors to reduce wear. Statically balanced to maintain constant airflow.

Lighting:

Recessed 2 pin fluorescent “cleanroom” type sealed 4 bulb lights – 125 ft. candle +/-20 ft. candles. Plastic prismatic lens cover maximizes light diffusion.

Controls:

Solid state airflow control, 70-120 fpm. 15A load capacity. Individual switches for motor & lights.
