FEATURES
A basic FLOW/CON diffuser system consists of a fabric diffuser connected to an air handler. It becomes a pressurized plenum. The external static pressure and velocity pressure at the inlet of the diffuser are used to inflate the diffuser and discharge airjets. The input air can be untempered, heated, or cooled. Airjet ports are positioned along the entire length of the diffuser, in any pattern needed to meet the air distribution and mixing requirements. The discharge velocity of the airjets is virtually the same along the length of the diffuser, and the many airjets entrap and mix all of the air in the surrounding area. Diffuser length can range from 10' to 500' or more. Diameters can be anywhere from 6" to 96" or more. The position of the airjet ports, the size and number of ports and the level of static pressure in the diffuser must all be balanced to design the best system for the application. A FLOW/CON air diffusion system can be a single, simple diffuser or a complex system including elbows, offsets, tees, transitions, wye branches, dampers, vertical drops, horizontal takeoffs and more. Each system is custom engineered to meet specific needs. Typically, a FLOW/CON air diffuser system has snap hooks attached for installation on steel cable.
There are three optional designs for FLOW/CON air diffusion systems: Powerflow, Softflow, and Microflow. The design differences are primarily in the size and number of airjets discharged from a diffuser, and the static pressure requirements. All three designs are very efficient at distributing air, but each has unique features that make it more effective for a particular application. Large airjets cause more extensive turbulence and noticeable air circulation well beyond their profile. With very small airjets, air movement is not noticeable beyond a few inches from the diffuser. FLOW/CON air diffusers can be made from a wide range of flame retardant fabrics. Most Powerflow and Softflow are fabricated with super tough, woven polyethylene. It is a rip-stop fabric that is coated for non permeability and to improve wearability. Coated polyesters are sometimes used for machine washability and aesthetics. Coated polyesters and fiberglass fabrics are also used for high temperature applications. Permeable polyesters and nylons are used for Microflow designs. Specific porosity levels are engineered to meet design requirements. The Evaluation Service of the Building Officials and Code
Administrators International (BOCA-ES) has evaluated the FLOW/CON
Air Diffusers manufactured by FOF INC. They have determined that
FLOW/CON Diffusers comply with the 1996 International Mechanical
Code Section 105 as an alternative material. The applicable tests
included:
Boca has issued Research Report 94-8 to document compliance of the FLOW/CON Air Diffusers. Only FOF INC. is authorized to use the report. FLOW/CON Air Diffusers are not UL Classified. This UL rating is not as comprehensive as the Boca Evaluation. It covers only surface burning. Click Here to Request Boca Report and Literature To prepare a proposal for you, we ask that you fill out a questionnaire on your project. If possible a sketch is also helpful. We then design one or more solutions to meet your air distribution requirements and provide you with a quotation. In the process, we may link you with one of our local representatives. |
