The Robertson ARV is designed to automatically provide its maximum exhaust area under fire conditions, whilst providing a fully weathered unit in its normally closed position.

Design features

• Coefficient of Discharge: As determined by independent tests is a minimum of 0.78. This result is based on tests of the largest ARV unit and were carried out in accordance with international standards.
• Maintenance testing: Regular maintenance testing of all automatic smoke/heat release ventilators is a standard building code requirement. ARV Ventilators incorporate the necessary facilities to enable this testing.
• Remote control systems: Can be provided with electrical or pneumatic remote control systems with zone control if required.
• Base types: Available with a Type A, Type B (to fit a soaker sheet), or Type C (curb fixing base).
• Materials: Can be supplied in a wide range of cladding materials including Versacor coated sheeting.
• ARV vents are designed to meet international building code standards.

Smoke/Heat Release Systems

To establish the most effective fire ventilation systems, Robertson in Australia has participated in several research programs, including a full scale Federal Government project in which 111 experiments were conducted in a study coordinated and managed by the CSIRO in an aircraft hangar in Darwin.

In 1978, Robertson was invited to participate in the formulation of the Standards on Smoke/Heat Release Vents, conducted by the Australian Standards Committee. By choice, all products developed by Robertson since the inception of the Standard comply with the requirements of AS2427-1983 and other international standards.

It should be noted that while all Robertson Smoke/Heat Release Ventilators have been designed, manufactured and tested to all current and relevant Australian Standards, these products are constantly reviewed in the light of any pertinent international standards.
