AN AIR HANDLING SYSTEM FOR A PAINT APPLYING ENCLOSURE

摘要

An air handling system for paint spray booth (10) includes an exhaust duct (28) which delivers exhaust air to an air divider (340). One portion of the exhaust air is fed to a vapour absorber (30) which removes organic vapour therefrom. The other portion of the exhaust air is fed to an air mixer (346) and is mixed with conditioned fresh air from a supply (348). The mixture is then fed to the paint spray booth (10) by way of its inlet duct (14). Since less than the entire volume of exhaust air is being stripped of organic vapour both the capital and operating costs of the vapour removal process are less than in an arrangement where all the exhaust air is treated.
