Evolution of the AR 600 high-speed door model, the AR 300 technical closure is suitable for small internal openings where a normal workflow is expected but without giving up the self-repair function of the closure. The high-speed door can therefore immediately resume operation thanks to the automatic restoring of the curtain. This model is excellent value for money.
STANDARD DIMENSIONS OF THE TRANSIT AREA:
Minimum dimensions: W 2000 x H 2000 mm
Maximum dimensions: W 3500 x H 3400 mm
Application: for internal use only
Opening speed: 0,7 m/sec
Standard metal structure:
top cross member in die-bent sheet metal made of galvanized steel thickness 1.5 mm, non-self-supporting, equipped with fixing plates to be bolted. Galvanized steel lateral jambs, fitted with slotted fixing brackets for adjustment.
Curtain: Tear-resistant, PVC, 900 g/m². At eye level, one row of transparent heat-sealed inspection windows. Electrowelded side sealing hinges.
Side slides: profiled in high molecular density polyzene housed inside the jambs. The polyzene is self-lubricating for perfect sliding of the curtain, designed with a special cut to let the curtain slip back in place in case of breakage (self-repairing system). They are also equipped with an exclusive lateral adjustment system with springs, for optimal tensioning of the curtain.
Resistance to bending: 100.000 bends without tearing
Tear resistance: 500 N
Tensile strength: 4000 N/50 mm
Wind resistance: Class 1 (30Kg/ m²) ~ 40Km/hr
Thermal resistance: – 20 °C to + 50 °C
Roller shaft: diameter 90 mm supported by ball bearings. Guard in galvanized sheet metal (painted in the colours indicated on request)
Drive unit: three-phase motor 400V-50 Hz with electric brake suitable for intensive use. Limit switch incorporated into the gear unit, easy to inspect and adjustable. Thermal circuit breaker for protection against voltage surges.
Gear reducer: with long-life lubrication and maintenance-free. Fitted directly on the roller shaft or driven by a transmission chain.
Emergency procedure: release rod for manual opening of the curtain in case of power failure (maximum height 2500mm). When the rod is engaged, a safety micro-switch automatically cuts off power to the motor.
CE UNI EN 13241-1 marking data:
- Operating speed - up to 0.7 m / sec
