Also searched as: ATEX High Speed Door
The Explosion-Proof High Speed Door is engineered for hazardous-area environments – chemical, petrochemical, pharmaceutical and grain-handling facilities – where the door’s drive must not become an ignition source. The key distinction is the motor: RAX offers an explosion-proof motor rated Ex d IIB T4 (motor-only Ex rating), paired with the same rapid, sealed curtain construction as our standard high speed doors.
It cycles like other flexible rapid doors – typically about 0.8-1.5 m/s for PVC rapid doors (industry synthesis) – with the difference being the Ex-rated drive rather than speed. RAX confirms the travel speed, zone suitability and sealing per project.
Important: the Ex d IIB T4 rating applies to the motor. The door assembly’s suitability for a specific hazardous zone (gas group, temperature class, ATEX zone) is confirmed per project against the applicable ATEX directives – RAX does not overclaim a blanket ATEX certificate for the whole door.
As a pure manufacturer, RAX builds each explosion-proof high speed door to your exact opening and RAL color – from prototype to container-load delivery order – with wiring diagrams and English manuals for your local installers.
Sources & honesty: RAX-company facts on this page (materials, 100,000-cycle fatigue testing, certifications held, warranty, lead time) are from RAX Door Technology’s approved brand brief. Industry benchmark figures (typical opening speeds, cycle-life ranges, EN 12424 wind classes, ISO 14644-1 cleanroom classes, competitor reference points) are drawn from our sourced category research (research/high-speed-doors.md) and are marked as industry-typical or attributed to the named manufacturer. RAX’s own measured speed, U-value, wind-class certificate and cleanroom class are confirmed per project by test – we do not publish them as generic figures. Fire resistance (EN 1634-1) and ATEX suitability are project-specific capabilities, not blanket certificates.

Provide clear opening width x height, headroom and side room – or site photos. We produce the confirmation drawing and confirm the feasible span against wind class.
Cycles per day, operating temperature range, wind exposure, and clean / cold / washdown / hazardous-area duty.
Target speed, thermal (U-value), wind (EN 12424), fire (EN 1634-1), acoustic or cleanroom class – we match the applicable standard and confirm by test.
Servo or VFD drive, sensing (radar / geomagnetic / light-curtain), safety edges and any safety-interlock or smart (WiFi/RS485) control needs.
Hazardous-area openings where the drive must not be an ignition source.
Zones with flammable vapors requiring an Ex-rated motor.
Combustible-dust environments needing controlled, sealed door operation.
Solvent-rich areas where ignition-source control is mandatory.
RAX supports full private-label production of the Explosion-Proof High Speed Door: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Product standard for industrial, commercial and garage doors – the harmonized basis for CE marking. Covers mechanical and power-operated safety, wind-pressure and water-penetration resistance, thermal (U-value) and air-permeability performance, with technical documentation retained 10 years.
Safety in use of power-operated doors – operating-force limits and entrapment protection, and the test methods behind our operator safety data.
Fire-resistance test method for door and shutter assemblies. RAX can engineer fire-rated curtains/panels (EI60/EI120) and arrange EN 1634-1 testing per project – a project-specific capability, not a blanket held certificate.
Any opening size within the High Speed Doors range – large industrial doors from prototype to container-load, full flexibility on order quantity. Share your opening width x height (or site photos) and our engineers confirm the feasible span, wind class and drive sizing, then produce technical drawings.
An explosion-proof rapid door cycles like other flexible PVC rapid doors – typically about 0.8-1.5 m/s (industry synthesis) – with the difference being the Ex-rated drive rather than speed. RAX confirms the travel speed and zone suitability for your facility in the quotation.
We are precise about this to avoid overclaiming: the Ex d IIB T4 rating applies to the motor (motor-only Ex rating). The door assembly’s suitability for a specific hazardous zone – gas group, temperature class and ATEX zone – is confirmed per project against the applicable ATEX directives. Tell us your zone classification and we will engineer and document the matching configuration.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Fire resistance (EI60/EI120) and an EN 12424 wind-load class are project-specific capabilities we test and certify per order against the matching standard – we do not overclaim a blanket rating.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production, under strict NDA.
