The Series 4000 Rapid Auto Roll Door (previously known as the Rolflex Door), is our most popular door, and is designed to be back in operation within seconds of accidental impact. A heavy duty door, the Series 4000 can save you, not only in containing your precious internal environment, but in downtime and repair costs due to this breakout feature with auto reset function.
With the ability to accommodate large openings up to 25 sq metres, this door is equipped with a unique counter balance system ensuring total control, and has full corrosion protection by zinc plating and powdercoating.
The panel is made from a highly durable, low porous Duraskin, and together with our unique aluminium wind rails, the Series 4000 has the ability to withstand strong wind, while still maintaining the breakout feature.
The Control system, unique to DMF, runs on single or 3 phase supply, and offers a full range of safety features, and programmable features, allowing the user to customise to suit the requirements.
Suitable for a variety of applications, the Series 4000 can be used in freezers operating down to -35° C, cleanrooms, warehouses, production areas, just to name a few.
It also comes with emergency opening in the case of power loss, by simply pulling on a brake release cable and lifting the door blade.
