An inflatable gasket is a flexible seal that can be inflated (usually with air or inert gas) to form a tight seal between two surfaces. When deflated, it retracts, allowing easy access or separation.

In pharmaceutical isolators, inflatable gaskets are commonly used to:

• Seal doors, glove ports, transfer hatches, etc.

• Ensure airtight containment of hazardous or sterile environments.

• Allow easy opening/closing without compromising the seal integrity.

Western polyrub inflatable seal for isolator door is made from high strength FDA approved silicone rubber which inflate radially outward. Because the shell of the unit is fabricated due to less gape and not machined, the machined acrylic or steel door will be made to a much tighter tolerance than the frame. This means there will be a enough seal gap.western polyrub seal is made with 25 % to 50 % inflation which cover that gap 

• The Western inflatable door seal is a reinforced elastomeric tube or without reinforced (depend on pressure)custom molded in a round concave, convoluted or flat configuration.
• It is designed to round out with the introduction of an inflation medium to form a tight barrier between a mounting and striking surface.

• When you feel the air as per pressure(chk pressure data).
• The seal quickly expands to the striking surface, effecting a positive seal.
• When the inflation medium is removed, the seal retracts naturally to the pre-inflated configuration.
• This position provides clearance for free movement of one or both surfaces.

• A very common inflation medium is regulated air.
• The specific parameters of the application determine the optimum operating pressure (please chk data in pressure certificate).
• In some applications, liquid or gel may be used as the inflation medium.
• Introduction of the inflation medium is through a stem which is usually a flexible high temp hose secured to an integrally molded fitting with a ferrule.
• A variety of fittings you can attach to the end of the hose.
• Why Use a western Inflatable door Seal? An inflatable door seal has several advantages over other sealing methods:
• Western door seal provides a leak-proof closure, yet allows clearance when needed.(so no need of perfect fabrication)
• Western seal minimize work on a design of the structure and hardware.
• The Western seal doesn't require fabrication for close machining and/or fabricating tolerances.
• Western seal also reduce replacement time

• Inflatable seals can be installed in different shapes; radially in, radially out, axially and any combination thereof.
• They will conform to many different contours.
• They are made in strips or round with closed ends or in continuous loops.
• The bend radii will vary from seal to seal and sizes if a very sharp or mitered corner is necessary, the seal can be molded to the exact configuration

In pharmaceutical isolators, inflatable gaskets are commonly used to:

• Seal doors, glove ports, transfer hatches, etc.

• Ensure airtight containment of hazardous or sterile environments.

• Allow easy opening/closing without compromising the seal integrity.

• Inflatable clamps designed with two sealed ends can positioned along the sides of the conveyor belt or rolls and inflated against the product to temporarily interrupt the flow while the jam clears downstream.
• Alternately, the bladders can be located underneath the conveyor and activated to release the contact between belt and rollers

Western polyrub silicone inflatable seal for use between the cover and base of a heat treating furnace. The seal includes an annular fluid-impervious member mounted on the base. brass Valves are provided to inflate and deflate the annular member. in the inflated position, the annular member extends between the cover and the base to provide a tight seal. The casing of the member is made of a metal or any other material, The use of bell-type annealing furnaces for heat treating coiled strips of material has become widespread in the art. These heat treating furnaces include a base of one or more pedestals on which the coiled strips of material which are to be heat treated are placed. An inner cover is placed over these coiled strips of material, and it is necessary in most instances to seal the coils within the inner cover to provide a controlled atmosphere therein.

Why inflatable seal:

• it gives 100% sealing no proper machining of lead easy to operate and install save replacement time and long life

Western polyrub have a technique to manufacture inflatable seals that can span gaps. To achieve this we adopt the Vacuum Membrane product. The seal is manufactured in an “inflated” state so that there is already a positive seal without pressure involved. Vacuum is applied to displace the profile and give clearances of section. Once the vacuum is released and a positive pressure applied there is a wide seal contact face giving gas tight levels of sealing. western Vacuum Membranes can be manufactured for radially in / out and axial orientations. The most common material for western Vacuum Membranes is Silicone, however other more exotic materials are available on request. These designs are particularly useful for sealing inwardly when large clearance is required, as standard inflatable seals can buckle and deform unless seal gap is extremely small in such cases. One common application is drum sealing within high containment areas.

A wide range of silicone inflatable seal for Inflatable Seal For Diverter Valve provides a solution for virtually every problem of material flow diversion in bulk solids conveying and processing.
