work by introduction of an inflation pressure into the cavity of the inflatable seals. This inflation pressure causes the displacement of the seals effecting a positive seal between the seals and the surface to be sealed. Once the seals inflation pressure is removed the seal returns to its uninflated position (memory).
Regulated air is the commonly utilized inflatable seals medium while in some applications pneumatic (gas) or hydraulic (liquid) methods are suitable. Inflatable seals offer versatile configurations in three different planes: radially in, radially out and axially.
Inflator-seals are an inflatable silicone seal (like a door seal or aperture seal) that can be inflated to accommodate a variable sealing gap. We manufacture inflatable seals and inflatable silicone seals in a relaxed/deflated attitude but when air pressure is applied, the seal either expands or rises up to meet the sealing face. When the pressure is released, the seal returns to its relaxed position.
Rubtech inflator-seals are made from high strength FDA approved silicone and are supplied in our corporate colours of transparent & red favored by the food industry. Other colours are available to special order.Applications:
- Sliding doors - a great benefit for this application. The seal automatically retracts away when air pressure is removed, allowing the door to travel freely
- Pharma-copia environments - inflator-seals provide an inflatable sealing solution where the risk of fabric contamination is unacceptable like fluid bed dryer, processor & coaters
- Food processing - ideal for oven door seals. In the event of accidental damage, the colour of the seal ensures that detection in the event of contamination is easily achieved
