Class Information
Number: 55/309
Name: Gas separation > With separating media bypass or system gas pressure relief (e.g., rupturable or deformable)
Description: Apparatus provided with means (1) to permit total flow of the system fluid directed through the apparatus to avoid the separating means, or at least one stage of serially arranged separating means, (2) to admit ambient air to the apparatus through other than the normal inflow path of fluid to be separated, or (3) to permit discharge or escape of system fluid to the ambient air through other than the normal gas effluent path.
