Allergen Control Enclosure
What is the Allergen Control Enclosure ?
The objectives of the Allergen Control Enclosure (ACE) are to protect both the operator and the surrounding area from allergen contamination whilst cage-cleaning operations etc are carried out. There is also a degree of work protection due to the ISO Class 5 laminar down flow air.
Further protection of the environment from odours and smells can be achieved with the addition of the optional exhaust carbon fan/filter modules.
The main application of the ACE is for cage cleaning. Here it is important to protect both the environment and the operator from allergens and it is also desirable to protect the cage from unnecessary background contamination.
Cage cleaning tables and industrial grade vacuum cleaners are also available to be used in conjunction with the ACE
How does it work?
The ACE has fans and HEPA filters situated in the rear wall of the enclosure. The HEPA filters are protected by high capacity dust filters situated upstream. The fans suck in air via the low mounted intake grilles and discharges through the HEPA filters to continue as clean air up the rear wall plenum. The air then enters the overhead plenum where most of it passes through a double skin flow screen to be returned as laminar down flow air. The remainder (approx 20%) exhausts via a roof mounted flow screen. This exhaust air volume flow then equates to the inward flow of air at the front of the ACE
The main advantage of the ACE is that it allows an unconstrained cleaning operation whilst maintaining high operator, environment and product protection. Also, this particular design has the main HEPA filters located in the back wall where they are easy to test and replace by comparison to overhead filters. This also means the down flow plenum can be very shallow, allowing maximum headroom in low ceiling areas.
Other advantages of the ACE are a digital control system with fully automatic fan speed control and fully alarmed displays
