Product Announcement from Clean Air Products
Clean Room Air Showers serve to protect your cleanroom environment from unwanted contamination.
Air showers can greatly enhance your cleanroom's performance by removing surface contamination from clothing and cleanroom garments. Gowning/changing room areas are the interface between a dirty "street clothes" environment and a clean room environment. Unfortunately, the changing or gowning process itself releases contaminants from street clothes that can settle onto the "clean" garments.
Air showers blow off and remove much of this contamination preventing it from entering the clean space.
An air shower in many ways can be compared to vacuum cleaner.
They are available in a variety of sizes, capacities and features; some work very well while others just seem to make noise.
To be effective, they need to have high cleaning force and power.
A good vacuum cleaner has high suction and airflow to pick up dirt. A small vacuum with low suction and airflow does little more than pick up a few crumbs. The same can be said for air showers. Some air showers (not offered by Clean Air Products) have a small blower/motor, low airflow and low pressure and are classified as under-powered devices. The Clean Air Products' CAP701 air showers offer the highest velocities combined with a large airflow rate to provide an air shower that quickly and efficiently cleans particulates from the surface of clean room garments. The air shower provides air flow of approximately 1900 CFM through 32 adjustable nozzles yielding a 7800 LFPM nozzle air velocity with optional 9100 LFPM nozzle velocities.
- Construction Materials
The CAP701 air shower is constructed of an all-metal, painted steel shell with no wood or plastic laminate and is entirely silicone free. The standard shower has a 16-gage steel shell, heavy-duty glass door and door closer. The shell and concealed air ducts are finished with a white powder coat paint which provides a strong, durable cleanroom-compatible finish. The all-steel shell design will stand up to the rigors of shipping, installation, use, and the occasional abuse of a high-traffic entry system. While we don't recommend it, you could hit the metal shell of the air shower with a hammer. It may dent or scratch the paint, but you would not break the cabinet as you would with laminated types of construction. The steel construction also reduces the chances of biological growth and contamination caused by systems using laminated particle board in the construction. NOTE: A typical laminated particle board air shower has the plastic laminate on the outside - but often the interior concealed air ducts are just painted over the raw particle board - leaving a rough surface finish that harbors dirt and biological contamination. As the particle board ages and deteriorates, parts will flake off, becoming another source of contamination. All-metal (painted steel or stainless steel) air showers provide the optimum in long term superior performance.
- Service Access
Service to the mechanical equipment, blower, motor, HEPA filter and pre-filter is easily done from the inside of the air shower through a hinged access panel located in the interior ceiling of the air shower. You don't have to penetrate the clean room ceiling surrounding the air shower for maintenance. Often the area around the air shower is not accessible because of ceiling filters, lights, ducts, pipes, walls or other equipment. Exterior-mounted service panels would make maintenance difficult or impossible in those cases. The unit's electrical control panel is conveniently mounted on the outside of the air shower above one of the entrances and is serviced from outside the air shower.
The air shower has a knock-down design that allows ease-of-installation and flexibility in use. The air shower can be shipped knocked down or completely assembled. When the air shower shipped knocked down, all parts will fit through a standard door. The air shower also offers an optional design that allows all the installation assembly to be done from inside the air shower.
Air showers are available in a variety of sizes and shapes to provide a cleaning system to meet your specific application.
Clean Air Products has been designing and manufacturing high quality cleanroom systems, components, equipment and supplies for a broad range of applications since 1969, including those in the semiconductor, biomedical, pharmaceutical and aerospace/military industries, among others.
Our comprehensive line of cleanroom products include:
These air showers are designed to clean off people or equipment prior to entering an adjacent space. Air is blown out through nozzles located on the side walls at approximately 90 MPH. The air blows into the interior space, where it cleans people or equipment. It is then recirculated through prefilters, an internal high pressure blower, and a HEPA filter, where it travels back to the nozzles on the internal sides of the unit. The Series 701 air showers are available in a variety of sizes and shapes to meet individual requirements.
