GREY WHALE is a filter bag manufacturer for OEM and replacement projects requiring exact fit, material selection and controlled production for industrial dust collectors.
We manufacture filter bags and cages that perfectly fit a wide variety of well-known dust collector brands worldwide. Eliminate leakage and ensure optimal sealing with our precision-engineered components.
We only use premium raw materials and advanced finishing treatments such as PTFE coating and membrane lamination to create OEM filters that last longer and perform better.
Get tailor-made solutions based on your specific flue gas temperature, chemical composition, and air-to-cloth ratio. Our engineers analyze your site conditions to recommend the ideal media.
Strict adherence to ISO9001-2008 and rigorous EGS online testing guarantees top-notch performance and durability for every bag and cage we produce.
Tailor the filter bags with the appropriate media (e.g., PPS for sulfur resistance, PTFE for extreme heat) to adequately handle the specific dust chemistry and temperature.
We calculate the optimal air-to-cloth ratio based on your dust load and system pressure drop requirements to ensure energy efficiency and long bag life.
Our range of filter bags and cages is customized to match the exact make, model, and cell plate dimensions of your existing dust collector.
We assess the abrasion level and chemical exposure of your application to apply necessary surface treatments, ensuring the filters won’t wear out or corrode prematurely.
We capture the industry, gas chemistry, temperature, dust load and collector specifications.
Fiber blend, finish, weaving and dimensions are selected by our technical team.
A functional sample is prepared for filtration, resistance and durability verification.
Trial feedback is turned into a final, documented specification.
Seam strength, weld consistency and exact dimensions are checked throughout production.
