Pass Box

Alfa provide Static and Dynamic pass boxes meeting the customer specific requirements and to the highest standards

In pharmaceuticals manufacturing facilities, it is essential to minimise man / material movement and avoid cross contamination between different classified areas to achieve desired classification and to maintain integrity of products and processes. Pass Box is designed to allow material transfer without much personnel movement. It also aids controlling ingress of particulate contaminants into clean room and between different classified areas.

Alfa makes Static and Dynamic Pass Boxes meeting the customer specific requirements and to the highest standards. Option of choosing the type of pass box depends on the containment level and transfer of material from one class of cleanliness to other class of cleanliness. We also supply the pass boxes suitable for flame proof areas.

Air Shower

Air Shower is designed to supply Class 100 HEPA filtered air at high velocity to remove particulate matter from the person entering into the Clean Room

Air shower is a self-contained air chamber installed at the entrance to cleanrooms in order to minimize the amount of particulate contaminants entering the cleanroom. Personnel move through the air shower while particulate contaminants are washed off with high velocity HEPA-filtered air jets. The high air velocity of 6000 FPM ensures efficient scrubbing action necessary to remove particulate matter. Contaminated air is then taken in through the base of the unit, filtered, and re-circulated into the chamber.

Two stage filtration- EU6 and EU 14

SS 304 doors with double walled flush glass view panels & door closer

Air cleanliness – ISO Class 5 (ISO 14644-1:1999 (E)

Air Velocities- 6000 fpm

Vibration Level – Minimum

Noise Level – Less than 70 dB

Fan Filter Units

Alfa Fan Filter Units (FFU) are designed for equipping individual workplaces or entire Clean room ceilings in a clean room environment. They are used to supply air and to reduce the particle concentration in Clean room facilities.

The FFU motors have sufficient power reserve capacity to overcome any additional pressure loss due to e.g. for raised floor, return air shafts, pre-filter, AMC-Filter or air cooler/heater.

Grill Opening

Grill openings and cutouts for other climate control equipment can be factory installed to induce labor costs and assembly time.

Pass Through Chambers

Pass through chambers minimize entry of contaminants (into the clean room) by providing a means for pick-up and delivery of products and supplies without personnel entry.

Productivity is increased because (clean room) workers remain clean and on the job while delivery personnel and contaminants.
