The five core reasons for the significantly shortened lifespan of the efficient filter element in high-humidity environments
\n1. When water comes into contact with the glass fiber filter material, it expands and blocks the air flow channels, causing the resistance to quickly exceed the limit.
\nThe core of the efficient filter element is ultra-fine glass fiber material, and the fibers rely on tiny gaps to intercept dust.
\nWhen high-humidity air and condensate water penetrate the filter material, the surface of the glass fibers adsorbs water molecules, causing the fibers to slightly expand;
\nThe fiber gaps become smaller and they stick to each other, narrowing the air flow channels, and the pressure difference rises sharply in a short period of time;
\nThe resistance quickly reaches twice the initial resistance threshold and can only be replaced in advance.
\nEven if there is very little dust, water vapor alone can cause blockage and failure.
\n2. Dust accumulates and gets damp and clumps, forming a permanent blockage layer.
\nThe dust in the air has hydrophilic properties:
\nThe dust attached to the inlet surface of the filter element gets wet and absorbs water, becoming compact and adhering to the surface of the filter material;
\nThe clumped dust cannot be peeled off with the airflow and forms a dense and non-breathable covering layer;
\nThe pressure difference remains persistently high and cannot be restored by wiping, and the filter element directly becomes unusable.
\n3. The sealant and frame structure of the filter element are affected by moisture and age, causing air leakage.
\nThe efficient filter element of Zhufa uses polyurethane glue to seal the filter material and the outer frame, which is the key to air tightness:
\nIn a long-term high-humidity environment, the sealant absorbs water, softens, foams, cracks, and detaches;
\nThere is a gap at the junction of the filter element and the metal frame, and the PAO\/DOP leak test is unqualified.
\nWater vapor will also corrode the metal frame of the filter element and the support frame of the metal frame\uff0c and the frame deformation further aggravates air leakage\uff1b
\nAfter air leakage\uff0c the particles in the clean area exceed the standard\uff0c and the filter element must be replaced.
\n4. Moisture promotes the growth of mold and microorganisms\uff0c damaging the filter material and contaminating the clean area.
\nHigh humidity + organic dust is highly prone to mold growth\uff1a
\nThe filter material\uff0c glue layer\uff0c and sealing strips grow mold spores\uff0c which penetrate the glass fiber filter net and directly damage the filtering structure\uff0c causing permanent leaks\uff1b
\nMold spores continuously enter the clean area with the wind\uff0c and the suspended bacteria and settled bacteria continuously exceed the standard\uff0c not meeting GMP \/ cleanroom specifications\uff1b
\nThe mold metabolic products corrode the glue seal\uff0c accelerating the failure of the filter element and presenting a risk of product contamination\uff0c making it impossible to continue using.
\n5. Moisture damages the electrostatic adsorption ability of the filter material and reduces the filtration efficiency.
\nThe efficient glass fiber filter element relies on physical interception + electrostatic adsorption for filtration\uff1a
\nHigh humidity in the air neutralizes the electrostatic charge on the surface of the filter material\uff1b
\nThe adsorption capacity for 0.3\u03bcm particles significantly decreases\uff0c and the filtration efficiency does not reach the H13\/H14 standard\uff1b
\nThe dust particles continue to exceed the standard\uff0c even if the pressure difference has not reached the replacement threshold\uff0c the filter element must be replaced.
\nNote\uff1a High-humidity environments also cause secondary losses
\nThe metal frame of the Zhufa is affected by moisture and rusts\uff0c causing the sealing deformation of the filter element frame\uff1b
\nCondensate water drips continuously onto the filter element\uff0c local filter material rots and is damaged\uff0c and direct leakage holes appear\uff1b
\nTemperature and humidity fluctuations repeatedly cause condensation and drying\uff0c alternating between hot and cold\uff0c dry and wet\uff0c accelerating the aging and cracking of the glue seal.
\nResumen
\nMoisture simultaneously damages the filter element in five aspects\uff1a air flow resistance\uff0c sealing structure\uff0c physical strength of the filter material\uff0c electrostatic filtering performance\uff0c and microbial contamination. Therefore\uff0c under the same dust conditions\uff0c the lifespan of the filter element in a high-humidity environment is about half shorter than in a dry and clean environment.<\/p>","protected":false},"excerpt":{"rendered":"
