Spring Frame

Spring frame (spring bag frame) is an essential accessory for external filter dust collectors. It comes in two types: with and without Venturi tube, featuring certain flexibility. Due to the limitation of indoor space for dust collectors, there is no sufficient space at the top of the dust collector to replace the dust frame. Therefore, spring frames or (interlocking) multi-section dust frames are adopted in the design.

Product Specifications

The spring frame diameter is generally less than 130mm, made by winding 5mm diameter wire, typically with 35 turns per meter after extension. The standard stretch lengths are 1.5M, 2M, and 2.5M. The surface is treated with zinc plating after processing. The spring frame design is robust and reliable, offering a longer service life.

Spring Frame Material: Low-carbon Steel Wire, Galvanized Steel Wire, Stainless Steel Wire

Surface Treatment: Galvanized, powder coated, corrosion-resistant treatment, and silicone spray coating.

Product Applications: Widely used in metallurgy, building materials, power generation, chemical industry, food, and incinerator industries.
