Air Showers
Standard Air Showers
Air showers quickly and effectively remove particles so that they will not be carried into your cleanroom. These decontamination air showers feature rugged construction and adjustable, high velocity air jets.
Low-Profile Air Showers
Low-profile air showers have a side-mounted blower assembly, HEPA filter and electrical components, making them ideal for retrofits or where ceilings can’t be penetrated.
Pass-Through Air Showers
Pass-Through Air Showers offer an effective way to remove surface-deposited particles from large materials as you transfer them into the clean room. They can be used with carts, conveyors, pallets and continuous-part operations.
The CleanPro® Advantage
Superior Performance
Some air showers have a small blower/motor, low airflow and low pressure. CleanPro® air showers have a high velocity and a large air volume rate for fast, efficient cleaning. Our 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.
Superior Construction Materials
CleanPro® standard air showers are 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-gauge 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. The steel construction also reduces the chances of biological growth and contamination caused by systems using laminated particle board in the construction.
Superior Service Access
Service to the mechanical equipment, blower, motor, HEPA filter and prefilter is easily done from the inside of the air shower through a hinged access panel located in the interior ceiling of the air shower. This is desirable because 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. Our electrical control panels are conveniently mounted on the outside of the air shower above one of the entrances, and is serviced from outside the air shower.
Optional Features
Although most air shower applications just require the basics: enter, cleaning cycle and exit, there are a large number of customizations available to suit any application. Examples include stainless steel shells for pharmaceutical applications, explosion-proof blower cabinets, key card access, fire alarm integrations, and motion sensor starts.
Important Installation Considerations
Most common air showers have a blower cabinet that must be suspended at 8' while the side wall air chases are attached. That means there will have to be some lifting mechanism to hold it in place, most often a forklift. You must account for not only installing the air shower in its final location, but also having a device capable of accessing that area.
How are Air Showers Shipped & Installed?
Air shower can be shipped fully assembled (on its side on the skid) or knocked down with the wall panels off from the upper blower cabinet, allowing the components of the air shower to fit through a standard 3' x 7' door opening when removed from the shipping skid. If the components are required to fit through a different size door, please indicate so in the quote request.
Air showers can be installed so the entire air shower sticks through the wall, with space around the air shower. This space is filled with an optional trim angle. The shower can also butt up against a wall with an opening large enough for the door and related end-mounted hardware (approximately 48" x 90"). Please request a quote before planning cut-outs, as different configurations and sizes may require different cut-out sizes. When the unit is butting against the wall, the contact point between the air shower and the framed opening is typically caulked or a small trim molding is applied. The exterior of the air shower would also have a trim angle.
What is the Typical Installation Process?
When shipped fully assembled on its side, the weight for an air shower is approximately 1,300 lb. Two eye bolts located on the top of the air shower can be used to assist in lifting. After standing up the unit, it is then moved into position and leveled using shim stock and is anchored to the floor (anchors to be provided by the installer).
When the unit is shipping knocked-down, the air shower upper blower cabinet is 650 lbs. The wall panels are 250 lbs. The knocked-down air shower needs room on the sides of the unit during the assembly process to install the 3/8" mounting bolts. To assemble the unit, the blower section is taken off the skid and raised into position. The two wall sections are then bolted from the outside onto the upper blower housing. At this point, the assembly is self-supported. The doors are attached, power is connected, and the unit is ready to run. Assembly is fast and uncomplicated. Each unit is shipped with a detailed manual. We do recommend using mechanical lifts to assist in the assembly process. Once the unit is assembled, no space is required on the sides of the unit. After the unit is assembled, moved into place, and the mounting is complete:
- An electrician needs to connect power to the air shower, start the unit, and check blower rotation.
- A sprinkler contractor needs to install the sprinkler.
- The installer touches up the paint (if needed).
- The installer adjusts the doors and door closers (if needed).
- The installer adjusts the magnetic door interlocks (if needed).
- The installer confirms that high-velocity air is flowing out the nozzles at approximately 90 MPH. If the blower is running backwards, air will still come out of the nozzles, but only at about 15 MPH. Blower rotation can also be confirmed by looking at the blower itself.
- The installer cleans the inside of the air shower and the interior floor space.
- The installer seals any seams with caulk (provided by the installer) as required.
Contaminating particles adhere to garments in two ways: Either by mechanical entrapment, or an electrical attraction. Cleanroom garments made from synthetic materials like Tyvek®, polyester, and nylon feature smooth surfaces that minimize the mechanical bond, making it easier to blow surface contamination off the garment in an air shower.
Natural fibers, like cotton, tend to shed particles, and have a higher mechanical bond with particulates, making them harder to clean. Synthetic garments can develop a static charge that can hold particles. Laundering your garments with anti-static agent in the final rinse will reduce the level of static charge, allowing particles to be more easily removed. Some garments are available with special built-in conductive fibers that can assist in keeping the surface charge to a minimum.
