Disclosed is a chamber which defines a constant gas environment for passing moving objects therethrough and which is in open communication with the outside. The chamber comprises an inlet zone, a central interior gas flow zone wherein the constant gas environment is maintained, and an outlet zone. All zones are in open communication and the inlet and outlet zones are in open communication with the environment outside of the chamber. The interior gas flow zone has ostensibly transverse laminar gas flow passing through it. The inlet and outlet zones are provided with a source of suction to create a pressure within each zone which is less than the ambient pressure outside of the chamber and wherein such pressures are substantially the same. The interface between the central flow zone and each of the inlet and outlet zones are held under conditions substantially preclusive of turbulent flow conditions. The chamber is ideally designed to cure vapor permeation curable coating compositions, although a variety of other applications exist for the chamber.
