For many years, MDH Defence has designed, developed and manufactured a variety of NBC filters for use in systems incorporated into combat vehicles, ships and shelters. Filtration systems are designed to actively reduce the threat from agents to acceptable levels within the defined area of protection. They must be designed to counter likely agents over considerable timescales with the minimum of maintenance and long mean times between failures.

The BIOQUELL Defence Naval NBC Filtration system can be utilised as an affordable and reliable system.

The NBC Filter Station comprises a frame onto which is mounted a large filter housing and an electrically driven fan. The system incorporates the NATO standard 300m3/hr naval composite filter. A small heater is installed within the filter housing.

This is designed to warm the inside of the unit and reduce relative humidity, hence prolonging the life of the charcoal within the composite filter. Air is drawn through the system by the fan and is discharged into existing air distribution ducting to provide the ship it's overpressure for collective protection. Control of this overpressure is achieved by a pressure relief valve which vents air not otherwise lost through general leakage.

Key Features

• Complies with NATO STANAG 4447 for filter efficiency.
• Utilises standard 300m3/hr NATO Naval composite filter.
• Pressure Relief Valve to control overpressure.
• Unit is available as 600m3/hr if required.
• Integral heater to reduce humidity and prolong filter life.
• Method of construction - mild steel or aluminium.

All filters are produced under strict environmentally controlled conditions

Advancement in filter filling techniques, together with special production equipment, have resulted in the improvement of protection levels against biological and chemical threats. The latest NBC filters are produced under strict environmentally controlled conditions to maintain maximum media efficiency. These improvements in techniques and controls have also resulted in an increased shelf-life of NBC filters to a period of at least ten years.
