The BSB A60 multiblade Marine Fire Damper is designed for use on marine vessels to protect the integrity of fire rated bulkheads and decks. Each A60 damper is controlled by an electrical failsafe spring return actuator combined with a thermoelectric tripping device (thermal fuse) and volt free contacts for remote status indication. The A60 damper can be used where the maximum system pressure is 2000 Pa and duct velocities do not exceed 20 m/s. The A60 Marine Fire Damper has been tested in accordance with EN1751 with case leakage conforming to classes A, B and C and closed blade leakage to class B.
Suitable for both vertical and horizontal applications, with airflow in either direction. MED certified for A60 fire performance. Conforms to the current Commission Implementing Regulation.

Maintenance
A60 Series dampers are designed for normal dry filtered air systems. A programme of planned inspections should be carried out to include full operational checks, correct interface with, and function of, any control systems, cleaning and light lubrication.
As a guide, this should take place on a maximum of six months intervals.
Reference should be made to BS 9999 for more information. Records of damper installation, location and maintenance log shall be kept on board the vessel. These inspection and maintenance programmes may need to be repeated more regularly if the dampers are exposed to inclement/dusty conditions or fresh air intakes. The frequency of such checks should be developed based on site experience.
