Air shower is a two doors walk-through dust removal system, which is fitted prior to cleanroom entrance. The purpose of setting up air shower system is to control the risk of spreading contaminants in the cleanroom environment by removing particulate matter on the personnel by throwing class 100 airflow. The air shower machine throws high velocity HEPA filtered air through jet nozzles which removes particulate matter (includes solid and liquid particles suspend in air and some of them are hazardous in nature). The contaminated air is again filtered and re-circulated. With-in seconds, the person entering into air shower comes out entirely cleans i.e. free from harmful dust. Electronics and Pharmaceutical productions and animal breeding laboratories are some of areas where air showers are extensively used.
We are V-Mac Enginners manufacturer in India. We have in house facility of design, construction and installation of air shower entry systems for laboratories, clean rooms and manufacturing areas etc. These systems are carefully constructed at our factory, tested at various parameters then dispatched to the client’s site. Our air shower cabinets are designed with corrosion resistant materials (Stainless steel or powder coated MS), fitted with easy to use controls and safety arrangements; filters are easily replaceable whenever needed.
Our air shower entry systems are custom designed and constructed as per requirements of the customers and sold at industry leading price in India.
NO. OF PERSONS PER CYCLE
Standard models are made only for 1 person per cycle. To meet the needs of large number of workers, we can also design air showers with 2, 3 and 4 persons per cycles. They can also be fitted in series and parallel to meet demand of large number of workers.
EXIT TYPE
Our air showers are available of throughout type entry-exit, L type entry-exit and one-way entry and two way exit type.
CONSTRUCTION
Made of only corrosion resistant materials; we use either high grade stainless steel anti-microbial properties or powder coated MS for construction.
DOORS
Two doors are fitted in a system, one at entrance and one at exit. Doors are also made of stainless steel or powder coated MS. Handles and hydraulic door closers are fitted for easy access of door. Electromagnetic interlocking allows opening of single at one time; thus, prevents unwanted contamination inside the machine. There is also emergency switch; by pressing it, both doors open immediately.
BLOWER
Properly balanced motor blower of standard make, fitted with suspension system for noise level reduction.
FLOORING
Flooring or platform is made of either Stainless steel or Aluminum with detachable anti-slip PVC mat or equivalent material.
FITTINGS
Over all fittings such as handles, hinges and wires etc. are of any reputed brand and ISI marked.
INSTALLATION
Our engineering team visits your site and installs the machine properly. Demonstration and training is provided to all relevant staff.
