Softwall Cleanrooms

Clean Air Products’ modular softwall cleanrooms are designed for functionality and reduced cost, while delivering all the benefits of modular construction. These tent-like softwall clean rooms are lightweight and easy to assemble. They can be installed as freestanding structures or hung from the ceiling of your building.

Unlike hardwall cleanrooms, our softwall cleanrooms enclosures are generally smaller, more portable, and can fit into tight spaces. The portable design makes it easy to move, disassemble, store, and use as a temporary cleanroom. They’re an ideal solution for anyone looking for a quick and easy way to expand their clean room operations.

Softwall Clean Room Size & Classification Options

We offer a full line of softwall modular cleanrooms in a range of classifications and standard sizes, as well as custom softwall cleanrooms to match your unique specifications. Our plastic cleanrooms use negative air pressure meaning that the air pressure outside of the room is higher than the pressure in the room. Negative air pressure is accomplished by having an air tight clean room that filters air out of the room.

Standard sizes for softwall clean room enclosures range from 4-feet by 4-feet up to 24-feet by 36-feet. Larger sizes or nonstandard dimensions can be designed and built to meet any space requirements. Because of their modular design, our softwall clean rooms can be expanded or reduced in size without disassembling the entire cleanroom.

Clean Air Products’ softwall cleanrooms are available in a variety of classifications. The most popular classifications range from Class 100,000 (ISO 8) to Class 10 (ISO 4).

Softwall Cleanroom Benefits

Clean Air Products’ standard softwall cleanrooms provide a number of benefits and advantages that make them an effective solution for any clean-critical application.

  • High functionality
  • Low cost
  • Durable yet lightweight
  • Modular designs for easy assembly and disassembly
  • Easy to reconfigure or expand
  • Portable and easy to relocate
  • Two mounting options (freestanding or ceiling-hung)
  • Ideal for smaller spaces
  • Use of negative air pressure

Unique Modular Construction 

The basic building block of our modular design is the ceiling grid framework. Made up of tubular steel beams with T-bar cross members, this interlocking ceiling grid system enables easy assembly and expansion of the clean room. The ceiling is supported by tubular steel legs at each corner and reinforced with heavy-gauge, triangular steel gussets.  The simple assembaly process gives you the option to make these plastic cleanroom tents tempory and portable.

Powered HEPA filter units, lighting systems, and ceiling panels are sealed to the grid with gasket material. 

Ceiling Height

Our softwall cleanrooms enclosures are available with standard ceiling heights of 8-, 9-, or 10-feet. Various custom heights are available, depending on your unique application requirements. A two inch minimum is required between the filter unit and the facility ceiling; standard filter unit height is 16 inches.

Cleanroom Size Considerations

Without a center support, the maximum size of Clean Air Products softwall clean rooms is 12-feet by 12-feet. Larger cleanrooms can be constructed with additional support legs within the structure. For example, a 16-foot by 20-foot clean room would require one internal support leg; a 20-foot by 32-foot softwall cleanroom would require three internal support legs.

Other options are available for clear spans without support posts. For example, ceiling-suspended modular cleanrooms eliminate the need for legs and columns altogether. A configuration like this allows for a clean room that can easily accommodate the equipment layout you need for maximum floor space utilization.

Softwall Cleanroom Wall & Door Construction

The walls of our standard softwall cleanrooms are manufactured from clear, flame retardant, 40mil thick vinyl. Low outgassing and static-dissipative materials are available upon request.
Most of our softwall clean rooms utilize vinyl strip doors for entry/exit doorways. Standard strip doors consist of eight-inch wide, 80mil thick strips, with two-inch overlap. To enter or exit, simply push apart the strips; strips automatically reseal as they come back together. Strip doors are pre-assembled and easy to mount to the frame.
