Benefits
AirBlock, the #1 specified curtain in the industry, offers versatility and reliability that cannot be found with any other product. AirBlock curtains can be used with framing to create a cleanroom, or also used independently within an existing cleanroom to create areas that are still cleaner. Combined with Simplex’s superior mounting systems, AirBlock curtains offer increased durability and functionality. AirBlock curtains offer easier access and the best protection.

AirBlock softwalls are constructed from four-foot wide sheets of vinyl in thicknesses from 40 to 80 mil. These sheets are RF welded to form either solid walls or movable curtains. They are especially suitable for enclosing portable frame systems or improving laminar flow areas above work spaces. Softwalls are also used to further divide existing clean rooms, effectively creating cleaner inner zones.

Features Include:
Largest selection of quality materials – Simplex vinyls come in a wide array of colors, thicknesses and properties.


Mounting systems
A variety of patented mounting systems, engineered for easy installation and maximum performance. Click here to see all Simplex mountings.
Sealed Corners
Wraparound seals eliminate air loss or particle penetration at the corners. Our thicker vinyls require no hems or sash weights, and provide systems that are cleaner looking, easily adaptable and longer lasting.
Entryways
Simplex offers a variety of entry options, including hinged and sliding doors and strip doors. By alternating clear and frosted vinyl, we eliminate sticking and air gaps and make entrances easier to walk through.
RF-Welded
Seams Simplex uses RF welding on all seams and attachments. Theses seals provide a permanent bond that is cleaner and stronger than sewing. Sewing vinyl seams perforates and weakens the material, and frequent cleaning only accelerates the process. The result is premature product failure and a source of contamination.

Standard Cleanroom Grade Vinyl
All Simplex vinyls are made from pure ingredients, no recycled materials. Simplex vinyls are formulated to be fire-retardant and low-outgassing. Refer to our data sheets for complete test results on the material required. Thicknesses: .040, .060, .080, .120, and .160 mil. Colors: Clear, frosted, white, amber tint, smoke tint, blue, grey, black and tan.

Reinforced Vinyl Coated Fabric
This tough, vinyl-coated polyester material is ideal for areas in your cleanroom or factory that are susceptible to frequent traffic and constant use. The vinyl is also perfectly suited for applications that require a Class 1 fire rating per ASTM E-84 flame spread and smoke test. Thickness: 18 oz. (25 mil)
Colors: White, black, blue, grey, red, yellow and translucent frosted.

Polysim 509 Non-outgassing, Static Dissipative Polyurethane
Polysim 509 is made from an inherently static-dissipative urethane that provides permanent, non-humidity dependent ESD protection for sensitive manufacturing conditions such as computer disk drives, microelectronics, optics and aerospace. There is no plasticizer used in Polysim, making the volatile condensable contaminants extremely low. Because Polysim is an alloy using high molecular weight materials, the static dissipation properties are permanent. It does not wear off like many other materials that use only a surface coating. Polysim is also Class 1 fire rated for flame spread and smoke test. Thicknesses: .030 and .040 mil.
Colors: Clear, white and black.

Static Dissipative Vinyl
ESD vinyl is built with permanent built-in inhibitors. Unlike topical coating, these inhibitors will not wear off and will last for the life of the curtain. Test result show surface resistivity of 1.8 x 1010 ohm/cm (ambient 50% R.H.) per ASTM D257.
Colors: Clear, frosted, white, black and amber tint.

Tested for Safety and Reliability
All Simplex softwall materials are fully tested. Test results are available for fire retardancy, ESD, outgassing, sound abatement, chemical resistance and light transmission. Refer to our data sheets for complete test results on the material required.

Laser and Light Blocking Curtains
These specially designed softwall and curtain systems are popular for enclosing or dividing areas for special processes, such as laser functions and procedures, photo lithography and other light-sensitive work areas. Simplex’s opaque black vinyl blocks out 100% of the light transfer. The matte finish reduces light refraction. Curtains are also available with foil inserts for use with more powerful lasers. Simplex amber tinted curtains filter out various degrees of blue, yellow and harmful ultra-violet light. Light wavelength tests are available for Simplex red and amber tint curtains.

Thicknesses: .040 to .080 mil
Softwall width: Any size
Strip widths: 8″ to 48″

Important Liability Disclaimer:
Due to the many different types of lasers, Simplex does not make any performance claims for the laser protection contained in any of our curtains used for laser applications. It is solely the end user’s responsibility to test samples of the curtains and their protective linings for performance and safety and to determine their usability in a given application.
