Analysis of MF Filter Applications in Blowers

As a core piece of equipment in the field of industrial fluid control, the MF filter performs multiple functions within blower systems. Its application value spans key areas such as equipment protection, efficiency optimization, and system stability maintenance. The following analysis details its specific applications across four dimensions:

I. Dust Protection at the Air Intake, Extending Equipment Life

Blower air intakes are prone to inhaling airborne dust, fibers, and other impurities. Long-term operation can lead to impeller wear, dynamic imbalance, and bearing seizure. The MF series high-pressure blower specific filter employs a 304 stainless steel sintered mesh or galvanized steel wire mesh structure, achieving 50-500μm filtration accuracy through physical interception. For example, the MF-8 to MF-32 series produced by Kunshan Shungang Electromechanical feature a double-layer vacuum sintered filter screen that can withstand 70μm particle impact, with a dirt holding capacity three times greater than ordinary filter screens. This effectively reduces impeller maintenance frequency and extends equipment service life by over 40%.

II. Modular System Integration, Adapting to Complex Working Conditions

Addressing the continuous operation needs of large blower units, the MFV series external fluid backwash filter demonstrates unique advantages. Its modular design supports multi-unit parallel connection. When the pressure differential in a unit reaches 130kPa, the system automatically switches to use an external clean fluid for reverse flushing, ensuring continuous filtration in other units. Application cases from Shanghai Minghao Electromechanical show that this system, used in residue oil treatment within the petrochemical industry, can stably handle media with viscosity <100cps, achieving an impurity interception rate of 99.2%, with a single backwash taking only 30 seconds, reducing downtime risk by 85%.

III. Precision Filtration Upgrade, Meeting Special Scenario Requirements

In high-cleanliness fields such as pharmaceutical fermentation and electronic chip manufacturing, the MF microporous filter, using 0.1-10μm PTFE filter elements, achieves a bacterial retention rate >99.99%. In the magnetic levitation centrifugal blower supporting system by Nanjing Cigu Technology, this filter serves as a front-end pre-treatment unit, reducing the particle concentration at the air intake from 300ppm to below 5ppm. This ensures the impeller operates in a contamination-free environment, increasing the equipment's energy efficiency ratio by 15%, while also preventing dynamic balance failures caused by microbial growth.

IV. Vibration Suppression Assistance, Enhancing Operational Stability

Blower vibration can lead to secondary issues such as seal failure and pipeline resonance. The MF filter reduces turbulence intensity at the air intake through optimized fluid dynamics design. Measured data shows that the MF series filter using a V-SLOT slit-type filter element can reduce the amplitude of intake pressure fluctuations by 62%. When used in conjunction with rubber vibration dampers, the overall equipment vibration value decreases from 12mm/s to 4.5mm/s, reaching the "Good" operating range specified in ISO 10816-1, significantly reducing failure downtime caused by vibration.
