Portable Ductwork
|
|
For some applications, metal ductwork may by either unavailable or too costly to install. In these situations, Portable Fabric Ductwork systems by FOF Inc. provide an excellent solution. Using state of the art fabrics, FOF has created ductwork that can be installed in existing buildings with minimal installation or maintenance costs. The fabric ductwork holds up to the toughest industrial conditions while delivering air at a rate of up to 75,000 CFM. Please give us a call to further discuss the possibilities of installing fabric ductwork for your particular application.
| Fabric Air Diffuser Systems |
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.
