Device used in machine tools for removing contaminants from air comprises housing having inlet for air to be purified, separating device, outlet, and secondary inlet for ambient air
A device for removing contaminants from air comprises a housing (2) having an inlet (3) for the air to be purified, at least one separating device (7, 8, 9) through which the air flows, and an outlet for the purified air. The housing has a secondary inlet (17) for ambient air which opens into the housing so that ambient air is fed to the air to be purified upstream of at least one separating device. Preferred Features: The secondary inlet is arranged directly downstream of the inlet into the housing. The secondary inlet is arranged at 30-60 deg to the flow direction of the air to be purified. The cross-section of the secondary inlet narrows in the flow direction.
