Hepa Filter Module & Accessories

RETURN AIR GRILL MODULE

Application

• Grille / Register with integral filter compartment to allow “room-side” replaceable filter service
• Remove particulate at the zone level, extending life of central filter stations
• Models for both surface or suspended ceiling system installations
• Return filter grilles are typically located near the floor in sidewall applications

Product Features

• Available in 304 or 316 stainless steel, aluminum, or steel materials
• All Cleantech return grilles are available as hinged, filter assemblies, including grid core and perforated units.
• Outer frame and inner grille assembly are attached with casing.
• Fittment shall be snap in/Magnet based/bolting type
• Arctic white finish is standard on steel and aluminum filter grilles. Stainless steel grilles have a satin polish finish on exposed frame surfaces only – blades are 2B mill finishated near the floor in sidewall applications

Options

• Removable grille option where grille separates from filter frame
• All filter grille accessories are available in steel, aluminum, or stainless steel (304 or 316) materials
• White epoxy
• Optional latches including knurled thumb screws or wire rings
• Opposed blade volume control dampers (Model OB1) can be different material than grille. Cable driven dampers available for remote operation.
• Factory supplied cleanable mesh filters – aluminum or stainless steel

Introduction

Fan filter unit (FFU) is air cleaning equipment to supply purified air to the clean room for manufacturing semiconductor, liquid crystal, etc. The installation space is the system ceiling grid. For a large clean room, the number of required FFU is from several hundreds to several thousands.

Concept of FFU development

1. To reduce running cost by saving energy;
   2. To reduce construction cost and term by thin, light and compact structure;
   3. To reduce initial cost by total design of clean room including noise spec. etc;

4. We development FFU units basing upon the above concept to meet all the requirements for constructing, operating and maintaining clean rooms.

Advantage of clean room with FFU:

1. The construction period can be shortened;
2. The degree of cleanness from class 10 to class 1000 can be set and the degree of cleanness can be set at each area;
3. Because the back in the ceiling is a low-pressure, the potential of the leakage is low;
4. Bay method or through the wall method is possible by the arrangement of layout of FFU;
5. The velocity of the air flow can be set at each area;
6. Flexible increase or change of the clean room is possible by the arrangement of FFU.

Features

1. Wind speed: 0.35m/s, 0.45m/s;
2. Noise: less than 55dB;
3. Power: 220V, 50Hz;
4. Highly efficient filter (filtration efficiency is 99.99%);
5. Material: armor plate, stainless steel;
6. Adjustable speeds;
7. Excellent performance ;
8. Using a highly-efficient centrifugal air blower;
9. Durable, low noise, low vibration;
10. Free maintenance
