Softwall Cleanrooms

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).

Benefits of Our Softwall Cleanrooms softwall cleanroom

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 Cleanroom 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.

Portable Softwall Cleanrooms

We offer softwall portable cleanrooms in a varity of sizes to meet your invidivual needs. These portable cleanrooms are lightweight, low-cost and easy to assemble, making them the ideal solution for mobile particle quality control. 

Select a Softwall Cleanroom Series

Modular softwall cleanrooms are tent-like structures that provide the same functionality as hardwall structures at a reduced cost. Since they are lightweight and easy to assemble, softwall clean rooms are easily transported and can be installed as freestanding structures or hung from the ceiling of your building.

Vertical Flow Modular Softwall Cleanroom CAP575

The CAP575 softwall cleanroom provides a cost-effective method of providing a quality particulate control enclosure. The system utilizes proven cleanroom manufacturing and design techniques to provide a lightweight, easy-to-assemble cleanroom system.

Hanging Vertical Flow Softwall Cleanroom CAP577H

The CAP577H hanging vertical flow softwall cleanroom is supported by ceiling hanging points, eliminating the potential interference of standing legs. The softwall cleanroom also features downflow ceiling filter units.

Free Standing Horizontal Flow Cleanroom CAP577FH

The CAP577FH freestanding horizontal laminar flow cleanrooms provide horizontal air flow via flow units that are built into one or more walls. The horizontal design allows for air to be pulled from the back of the unit where a fan module pushes the air through a HEPA or ULPA filter.
