Inflatable Seals for Horizontal or Vertical Sliding Doors - Pneuma-Seal®

Doors and other closures can be positively sealed by using PNEUMA-SEAL. The seal is inflated with air or other fluid by a pressure- regulated supply system (which can also be furnished by Presray). When pressurized, the seal conforms to uneven surfaces and provides an efficient, reliable barrier to dust, moisture, contaminants and / or pressure differential.

Compression Seals & Gaskets

Compression seals, gaskets, tubing, etc. can be configured in practically any shape or size depending on the application. Compression seals can be simple round shapes or can include square corners with fabric reinforcement. Many different materials may be used depending on the application. It's ultimately important to ensure that the seal is specifically design for the application. Over engineering can result in cost overruns; under engineering may cause seal failure.

Bladder Clamps - Pneuma-Cel

Pneuma-Cel bladder clamps provide a different way to handle common clamping and actuating needs. Constructed of a high quality, durable EPDM rubber, Pneuma-Cel bladder clamps allow for soft, conformal clamping of delicate and/or irregularly shaped parts and are optimized for high cycle life and prolonged wear. Clamping pressures (up to 200 lbs-force) can be dialed in by either changing the internal bladder pressure or modifying the overall contact area (see technical info below).
