Xinxiang Filter

Description:
Tie rod flame-retardant antistatic filter cartridges are provided with a central through hole for tie rod installation. During assembly, the tie rod runs through the cartridge, and nuts or quick-release handles compress the end caps to fix the filter inside the filter chamber. This connection structure features compact layout and adjustable compression force, widely applied to upgraded SLM 280 machines, high-end continuous production equipment and certain aerospace-grade devices.

This product adopts asymmetric sintered filter media technology with flame retardants and conductive fibers blended in one piece, achieving UL94 V-0 flame retardancy grade and surface resistance ≤10⁹Ω. Complying with EN 1822 standard, it reaches H13-H14 filtration grades with filtration efficiency of ≥99.95%–99.995% for 0.3μm particles. The sintered plate structure enables a service life up to 20,000 hours, greatly cutting replacement frequency.

Core Technical Advantages

Asymmetric sintered filter media technology: The asymmetric sintered media features smooth surface for easy dust shedding, enabling online cleaning via pulse backblowing. Flame-retardant and antistatic properties are integrally sintered into the media without peeling or performance degradation.

Intrinsically safe explosion-proof design: Conductive surface treatment and V-0 flame retardancy are equipped. Matched with the equipment inert powder injection module, it neutralizes reactive metal powders in real time with inerting efficiency ≥99.9% to meet safety standards.

FAQ

Q1: What are the differences between sintered plate filters and standard pleated filter cartridges?

A: Sintered plate filters adopt asymmetric sintered media with high structural rigidity, integrally sintered flame-retardant and antistatic performance, reusability after cleaning, and a service life of 5–10 years. Conventional pleated filters are disposable with a lifespan of only several hundred to several thousand hours.

Q2: How to guarantee uniform compression force for tie rod filter cartridges?

A: Tighten nuts with a torque wrench to the torque specified in the equipment manual for full, even contact between end caps and sealing surfaces. Insufficient torque causes leakage, while excessive torque may crack filter end caps.

Q3: Does this filter cartridge support online backblowing cleaning?

A: Yes. Online filter cleaning can be realized by matching with the equipment pulse backblowing system without shutdown or disassembly.
