The Thermac Spray Unit has been designed to conform to the British Standard for equipment used in the controlled wetting of asbestos containing materials; BS8520.1.2009. The low pressure spray unit will suppress the release of airborne Asbestos fibres by delivering a fine mist of surfactant mixed with water at a maximum pressure of 3bar. The ratio of water to surfactant is typically 10%. This can be delivered through either 1 or 2 spray guns. The unit is also supplied with six different spray nozzles, which all give different spray patterns. The tank capacity is 50 litres.
