Abstract
A processing apparatus for compressed air comprises a body defining inlet and outlet passages leading to a bowl supported by the body. The bowl is of composite construction comprising a flexible inner bowl and a high impact strength outer bowl formed from polycarbonate for protecting the internal bowl from external damage. The inner bowl has an annular flange trapped between the outer bowl and the body to form a gas-tight seal between them, and is formed from a material which will protect the outer bowl from solvent and/or chemical attack. The outer bowl has a small vent to atmosphere to allow controlled venting of the compressed air in the event of inner bowl failure without allowing fragments from the inner bowl to pass through the vent. Both bowls are made of translucent or transparent materials so that the contents of the inner bowl can clearly be seen.
