Xinxiang Filter

Description:
Tie rod antistatic filter cartridges are designed with a central through hole for tie rod installation. During assembly, the tie rod penetrates the filter cartridge, and nuts or quick-release handles compress the end caps to fix the cartridge inside the filter chamber. This interface features compact structure and adjustable clamping force, widely applied to upgraded SLM 280 machines and various custom filtration equipment.

The filter media is treated with flame-retardant and antistatic composite treatment, with surface resistance ≤10⁹Ω to meet explosion-proof safety standards. Compliant with EN 1822 standard, it reaches H13-H14 filtration grades with ≥99.95%–99.995% capture efficiency for 0.3μm particles and initial resistance ≤220Pa. The tie rod compression structure delivers stable installation and effectively prevents gas bypass leakage.

Core Technical Advantages:

Central compression via tie rod: A central tie rod hole runs through the cartridge; the tie rod is secured by nuts or quick-release handles after threading through. Adjustable clamping force guarantees tight contact between end caps and equipment sealing surfaces.

Long-lasting antistatic performance with embedded conductive fiber mesh: Conductive carbon fiber mesh (3%–5% carbon fiber content) is evenly embedded inside the media to form a 3D static dissipation network. Surface resistance is stably maintained at 10⁶–10⁹Ω without degradation of antistatic properties.

Intrinsically safe explosion-proof design: The filter surface undergoes conductive treatment, and the whole equipment complies with explosion-proof specifications. The inert powder injection module neutralizes reactive metal powders in real time with inerting efficiency ≥99.9%.

FAQ

Q1: How to ensure uniform clamping force for tie rod filter cartridges?
A: Tighten nuts with a torque wrench following the torque value specified in the equipment manual to achieve tight, evenly stressed contact between end caps and sealing surfaces. Insufficient torque causes leakage, while excessive torque may crack filter end caps.

Q2: Does this filter cartridge support online backblowing cleaning?
A: Yes. Online cleaning can be realized by matching with the equipment pulse backblowing system to further extend service life.
