Technical Advantages:
• Ultra-high precision filtration: 5μm filtration accuracy (β value ≥ 200), 99.9% pollutant retention rate (in line with ISO 16889 standard).
• Pressure and impact resistance: spiral steel skeleton + multi-layer glass fiber filter material, withstand 3.0MPa high pressure impact, no deformation and leakage.
• Long life design: the pollution holding capacity is increased by 40%, supporting 3000+ hours of continuous operation and reducing the replacement frequency.
• Wide compatibility: compatible with Parker, HYDAC, Bosch and other mainstream brand filter housings, supporting OEM customization.
Filter Material:
HPQ220275L40-25MB oil filter is a high pressure filter element,the end caps and center tube are used corrosion resistant steel and all the filter can bear 3000 psid pressure with high performance,increasing efficiency,keeping fluids clean,and ensures smoother operation. HPQ220275L40-25MB oil filter is engineered to ensure your hydraulic system operates smoothly,offering a versatile solution for various applications.
• All glassfiber media aggregator combines deep particle filtration with deep coalescence structure.
• The all-glass fiber design has a continuous thinner dielectric layer to achieve deep filtration of particles.
• The composite glass fiber and fold medium coalescers mainly remove particles from high surface area fold cores.

Filter Features:
We make HPQ220275L40-25MB oil hydraulic filter is Beta grade. Excellent filtration performance. The Beta X = 1000 number means that for every 1000 particles of size x in the fluid, on average only one particle will pass through the filter.

Filter Wash:
HPQ220275L40-25MB hydraulic oil filter is stainless steel mesh element can be cleaned again after use,it can save you much cost.However,only a certain cleaning level (percentage) can be achieved.For best results,components should be cleaned using professional equipment.But cleaning results are unpredictable.It depends a lot on various conditions.

(1) Dip the filter element in light oil and rotate thoroughly.
(2) Clean off dirt by scrubbing the element with a brush parallel to the pleats.
(3) Clean off dirt with an air spray gun.
(4) Rinse well.
(5) Dry using an air spray gun.
Notes:
It must be noted that during each cleaning process,approx. 80-90% of the initial filter area can be recovered each time,that is,after 4-5 cleaning cycles,the result (cleaning cost and service life) may not be economical.We will be happy to send you the operating manual with further information on cleaning.
