Abstract

A trap device (18) is described for removing particulates from a gas stream drawn from an enclosure by a vacuum pump. The trap comprises a casing (28) having an inlet (16) connectable to the enclosure for receiving the gas stream therefrom and an outlet (20) connectable to the vacuum pump for exhausting the gas stream from the casing. A cartridge (36) removably insertable into the casing (28) has an inlet through which the gas stream enters the cartridge and an outlet through which the gas stream leaves the cartridge, the cartridge housing at least one filter element for removing particulates from the gas stream passing through the cartridge.
