Product Features:
Explosion-proof model
All metal powder anti-rust thick body, square frame welded structure is more solid and stable, durable.
Metal cross-flow fan wheel, provide higher air volume, stable air output and better isolation effect.
This air curtain is fully certified for explosion-proof operation, holding both the Whole Unit Explosion-Proof Certificate (No. CJEx23.0770X) and the Motor Explosion-Proof Certificate (No. CJEx23.0733X).
Designed with an integrated explosion-proof terminal box and a certified pure copper motor, it has undergone rigorous lab testing, demonstrating reliable performance for over 8,000 hours without failure. The unit carries the explosion-proof marking Ex dbIIC T4Gb, which represents a higher safety rating than standard explosion-proof equipment (Ex dbIIB T4) available on the market.
Suitable for use in Zone 1 and Zone 2 explosive gas atmospheres, this air curtain is ideal for demanding settings such as biopharmaceutical plants, chemical processing facilities, laboratories, gas stations, warehouses, and other hazardous locations where safety cannot be compromised.
This air curtain is fully certified for explosion-proof operation, holding both the Whole Unit Explosion-Proof Certificate (No. CJEx23.0770X) and the Motor Explosion-Proof Certificate (No. CJEx23.0733X).
Installation height: 3-5m.
Application: for refinery, chemical factory, electronic factory etc.

Solution
Making life more comfortable inside
Theodoor Air Curtain produces a high speed air current, dividing the inside and outside of the room into two independent temperature zones with the result that levels of interior air conditioning is maintained and the air is purified whilst energy is saved. Summer heat, winter cold, dust, insects, smoke, unpleasant odors and exhaust fumes are all kept out.
Prevent the loss of cool or warm air whilst economizing on electricity.
Efficient dust and insect-proofing..
Protect against smoke and noxious fumes.
Accelerate air circulation


Founded in 2002, Theodoor is lccated in Guangzhou innovation and development new area-Sino-Singapore Krlowledge City (SSGKC) with an area of 30,000 square meters. we have modern production workshop,applying the most advanced industrial equipments and detecting instruments to provide produa manufacturing precision and stability of extremely reliable guarantee. Theodoor has fu11 series procluc which meet dlfferent customizec demand in different countrles or areas.


Provide you the unusual confort experience
Theodoor Air Curtain adopt non-isometric quiet impellers to avoid the maximum noise frequency areal. Combined with scientific airflow design, it can redece noise effectively under stable operation. The working noise is around 50 dB which is as quiet as the office.
