Screens are generally installed at outlets of axial flow reactors to prevent processed media from escaping vessels.

Johnson Screens® outlet screen baskets and collectors serve as ideal solutions for this application. Manufactured from 304, 316, 321 or 347 stainless steel, or custom metallic materials as requested, the screens adopt specialized cross welding between Vee-Wire profiles and support rods. This structure effectively resists collapse and deformation under extreme loads and high temperatures.

Available in integral or split designs, the products can be installed through maintenance manholes. The minimum slot opening reaches 0.01 inch / 0.25 millimeter, enabling direct retention of fine catalyst particles. Despite narrow individual slots, the overall open area exceeds that of assemblies combining perforated plates and conventional mesh, which effectively improves process efficiency.

Superior performance of outlet collectors relies on reasonable diameter-length ratio and lateral-to-top open area distribution. We offer professional design optimization support.

Vee-Wire® outlet collectors hold catalyst directly without intermediate inert ball layers.

With exclusive structural design and cleaning performance, these collectors are applicable for high-purity gas service.
