LF/P3266 Polyester Cartridge Filter PTFE Membrane Pleated Filter Cartridge For Powder Coating & Abrasive Blasting Dust

Product Overview

For sticky, easy‑to‑cake fine dust generated in powder‑coating and pigment production workshops, ordinary cellulose filter‑elements are easy to form dust‑cake and lose cleaning effect. polyester cartridge filter model LF/P3266 is one typical solution inside Air Cleaning product series. It adopts 100% spun‑bond polyester media; PTFE membrane surface‑treated version is optional. The material features water‑repellent, oil‑repellent property and good dust‑cake‑release performance, partial versions support washing and repeated use. It is installed inside pulse‑jet dust‑collector equipment, intercepting powder‑coating over‑spray powder, blasting abrasive dust, pigment fine dust and welding sticky smoke particulates, widely applied for surface‑treatment workshops and paint‑coating factories.

Production‑Workshop Actual Application

Powder‑coating production line is the core‑application scenario: over‑sprayed coating powder has strong adhesion, common filter‑media is easy to be pasted by fine powder, resulting in frequent blockage. LF/P3266 with PTFE membrane greatly improves dust‑cake shedding performance during pulse‑jet blowing, extending filter‑element service cycle. Abrasive‑blasting workshops produce a large quantity of sharp mineral abrasive fine dust; high‑strength polyester‑media resists particle abrasion and reduces media‑damage risk. It is also used for pigment, dye production workshop, wood‑working fine‑dust collection. It matches multiple‑specification pulse‑jet filter‑housing; when users upgrade existing dust‑collector consumables, they can replace old‑style cellulose filter‑cartridge with LF/P3266 polyester version to improve anti‑sticky‑dust capacity. It can be used as consumable spare‑part for cartridge dust collector.

Core Product Advantages

Spun‑bond polyester substrate owns good mechanical strength and abrasion‑resistance. After PTFE membrane surface‑treatment, filter‑surface forms smooth non‑stick layer; dust cake can be thoroughly blown‑off in pulse‑cleaning cycle, avoiding permanent pore‑blocking. The material can bear operating‑temperature up to 120℃, adapting medium‑temperature dust‑gas working‑condition. Partial specifications support water‑washing regeneration to lower consumable‑replacement cost. Hot‑melting welding‑process without adhesive avoids secondary pollution caused by glue‑volatilization under temperature‑rise condition. Multiple end‑cap sealing options adapt different dust‑collector housing installation requirements.

FAQ

Q1：What is the difference between ordinary polyester LF/P3266 and PTFE‑membrane version?
A1：PTFE‑membrane‑treated version has super‑anti‑adhesion capacity for sticky dust such as powder‑coating; ordinary polyester is suitable for dry non‑sticky abrasive dust to control project cost.

Q2：Can LF/P3266 polyester filter cartridge be washed and reused?
A2：PTFE‑membrane version supports limited‑times gentle water‑washing regeneration; it cannot restore brand‑new performance completely, periodic replacement is still required after multiple washing cycles.

Q3：What is the maximum‑temperature working‑limit for LF/P3266?
A3：The maximum continuous operating‑temperature reaches 120℃, not applicable for long‑term over‑120℃ high‑temperature flue‑gas condition.

Q4：Can LF/P3266 directly replace original cellulose filter‑cartridge on existing dust‑collector?
A4：If outer‑diameter, inner‑diameter, length and installation‑interface dimensions are consistent, it can realize direct drop‑in replacement without modifying equipment housing.

Q5：Do you have other length‑specifications of polyester pleated filter‑cartridge besides LF/P3266?
A5：We supply LF/P‑series full‑size specifications including LF/P3566, LF/P3288 etc, please provide housing‑dimension to confirm suitable model.
