Softwall Clean Rooms offer an economical way to provide a Cleanroom environment. Rooms are easy to assemble or disassemble, portable, expandable and versatile.
Environments are available from Class 10-100,000 (ISO 4-8). Change rooms can be added internally or externally. Rooms are expandable should your requirements change in the future.

All rooms are completely self-supporting requiring no ties to your facility. Adding castors allows them to be positioned after assembly. They also allow one room to serve several locations.

These are modular Clean Room systems constructed using an aluminium / steel frame (MS/Stainless Steel) with antistatic vinyl curtains surrounding the work area. Both indigenous and imported framing options are available.

These softwall Cleanrooms are Equipped with Fan Filter Units. FFU takes air i through pre-filters from the top of the Cleanroom and discharges it into the enclosure. In this system return air is not taken back to the FFU, from the enclosure the excess air bleeds through the space provided below the vinyl curtains. Thus Positive pressure is maintained within the Cleanroom, this prevents the entry of contaminants.

HEPA FILTER (Clean Room)MODULES

Clean Room Modules are HEPA filtration systems that cater to the "Small Clean Room" requirements of Clients who work on a limited budget and for applications where a full fledged Clean Room, involving major site alterations and costs is not possible or not necessary. To meet these requirements, MARK has developed HEPA filter Modules each of the modules has a specific purpose as detailed below.

The Positive Pressure Module feeds fresh air into the room after HEPA filtration; Recirculation Module or the Room Air Dilution Module recirculates room air through the HEPA filter in repeated cycles resulting in dilution of the concentration of contaminants in the room; the AC connectable Module filters the cooled air from the window air conditioner in a HEPA filter and supplies sterile air to the room.

A combination of the modules described above helps in achieving the desired cleanliness level in the room.

Salient Features:

Class 100000 to Class 1000 achievable.

Ideal for rooms of area 250 SqFt or less

Suits budget, results match conventional systems

The cabinet is made of CRCA (MS) sheet with powder coated finish. Standard widths are 36”, 42” & 48”. Non-standard sizes are also available.
Pass Boxes or hatches are material transfer systems between rooms. These are installed on the common wall between two rooms and transfer of material takes place without exchange of air between the rooms. This is achieved with an interlocking arrangement that ensures that only one door in the Passbox can be opened at a time. These Pass boxes are effectively and widely used in Clean Rooms mainly in Hospitals and Pharmaceutical companies where cross contamination has to be avoided. Fluorescent/CFL lamp is provided. Material of Construction : SS304 or CRCA (MS) powder coated
Two types of Pass Boxes are available STATIC & DYNAMIC.
A Static Pass Box is a material transfer hatch with a two door arrangement, installed in a common wall between two rooms, one door opening into each of the rooms. An interlocking arrangement is installed in the Pass Box to ensure that only one door can be opened at a time. The interlocking arrangement could be mechanical or electromagnetic.
A Dynamic Pass Box incorporates a HEPA filtration system integrated in a Static Pass Box. The HEPA filter-blower switches On whenever a door is opened and switches Off whenever a door is closed. The entire system is controlled by a circuit with sensors and micro-switches. The interlocking arrangement is electromagnetic type. This type of Pass Box is installed between rooms that are not of same Cleanliness level, i.e, between Class 10000 room and a Class 100000 room and a Clean Room and an unclassified area.
