The RAX Inflatable Dock Shelter uses pneumatically inflated air bags — typically head bag, side bags and sometimes a bottom seal — to form a tight, conforming seal around the trailer body at the loading dock. Unlike compression foam pads that rely on trailer pressure against the foam, inflatable shelters actively pressurize to fill gaps around irregular trailer shapes, making them the preferred sealing solution for cold-storage, food-grade and pharmaceutical docks where temperature leakage and contamination must be minimized [ESTIMATE].
Inflatable shelters are constructed from flexible, airtight PVC-coated fabric (industry-typical 0.9–1.2 mm thickness) supported by a rigid aluminum or galvanized steel frame [ESTIMATE]. A small continuous-run blower maintains air pressure during truck loading/unloading, compensating for trailer movement. RAX manufactures inflatable dock shelters to your dock opening dimensions and trailer profile — from prototype to container-load delivery order — with technical layout drawings for your local installation team.
Air-filled bags (head, sides, bottom) inflate to conform to the trailer body shape, creating a tighter seal than compression foam pads — especially for irregular or damaged trailer bodies.
The preferred dock seal type for cold-storage and frozen-food docks where even small temperature leaks cause energy loss, condensation and product spoilage [ESTIMATE].
Small centrifugal blower maintains air pressure throughout loading/unloading; low power consumption (~0.37–0.75 kW) [ESTIMATE]; some designs use a blower with backup battery for pressure continuity.
Airtight, UV-resistant PVC-coated polyester fabric (industry-typical 0.9–1.2 mm); cold-storage compounds remain flexible at sub-zero temperatures [ESTIMATE].
Galvanized steel or aluminum frame with hinged side curtains for maintenance access; frame mounted to the dock face around the opening.
English installation manual + technical layout drawings; blower pre-wired and tested; FOB Tianjin or Qingdao, FCL & LCL.
Every unit is engineered to your dock. Figures marked [SOURCED] (with the source) or [ESTIMATE] (industry-typical, not independently verified for RAX) are market-reference values in the Basis column; your RAX unit’s final figures are confirmed on the technical layout and quotation.

Sizing note: Inflatable shelters are the premium sealing option for temperature-sensitive docks. If your dock handles ambient goods only and trailer contact pressure is consistent, a compression foam dock seal may be more cost-effective. Send your dock opening dimensions and trailer profile for a shelter type recommendation.
Width and height of the dock opening. This determines the shelter frame and bag sizing.
Typical trailer body dimensions and rear-door configuration. Inflatable shelters excel with varied or irregular trailer shapes.
Ambient, chilled or frozen? Cold-storage docks need the cold-compound PVC fabric.
Blower requires 220 V / 50 Hz single-phase. Confirm power point location near each dock position.
RAX supports full private-label production of the Inflatable Dock Shelter: custom frame sizing, fabric color, branded blower housings, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
RAX’s held CE certification for the industrial door and operator safety scope — relevant when you source the shelter together with the dock door as one thermal-seal package.
Certified quality management across the whole factory, with SGS material reports and Product Liability Insurance.
Inflatable shelters are widely specified in food-grade and cold-chain docks; RAX fabric and frame materials are compatible with HACCP-aligned facility requirements [ESTIMATE].
Air-filled bags (head, sides and optionally bottom) inflate via a small continuous-run blower to conform to the trailer body shape, forming a tight pneumatic seal. The blower maintains pressure throughout loading/unloading, compensating for trailer movement.
Yes. Inflatable shelters are the preferred seal type for cold-storage and frozen-food docks because the pneumatic seal conforms to irregular trailer shapes better than compression foam, minimizing temperature leakage. RAX offers cold-compound PVC fabric validated to −30 °C.
Industry-typical inflatable shelter blowers run 0.37–0.75 kW on 220 V / 50 Hz single-phase [ESTIMATE]. Power consumption is low — the blower runs continuously but draws minimal current.
PVC-coated polyester fabric (0.9–1.2 mm) is UV-resistant, abrasion-resistant and designed for years of dock operation [ESTIMATE]. Cold-storage compounds remain flexible at sub-zero temperatures. RAX supplies replacement fabric panels within warranty.
