Washable Synthetic Pocket Filter | Needle Punched G3 G4 Bag Filter
Experience long-term filtration value with our Recycled for application Primary Pocket Filter. Utilizing premium needle punched filter media in white, green, or blue, this synthetic pocket filter is designed to be recycled for application multiple times, significantly reducing maintenance costs. Its low resistance profile and robust fiber density ensure stable G3 / G4 class efficiency, making it a sustainable choice for industrial air handling units requiring frequent cleaning and reuse.
Product Key Features
Recyclable Design: Recycled for application and reusable multiple times, cutting down operational waste.
Strong Media Integrity: Features green and white needle punched filter media for superior tensile strength.
Moisture Resistance: Capable of operating in 80% maximum humidity, ideal for varied industrial climates.
Low Drag Efficiency: Optimized at a 70Pa initial resistance to lower fan energy consumption.

Material & Craftsmanship
Media Color: Available in white/green and white/blue and white.
Technical Fabric: Needle punched or pre-filter media with 35-45% (G4) efficiency.
Temperature Limit: Stable operation up to 80°C maximum operating temp.
Applications
Food & Beverage (High-Moisture)
Challenge: Standard filters collapse or mold in high humidity.Solution: Moisture-resistant media thrives in 80% humidity and is washable for hygiene.
Pharmaceutical Pre-filtration
Challenge: Frequent replacements lead to sky-high costs.Solution: High tensile strength media captures heavy dust and is reusable, extending HEPA filter life.
Metal & Grinding Workshops
Challenge: Abrasive or oily dust clogs filters rapidly.Solution: Needle-punched fabric survives harsh cleaning. Wash and reuse to slash waste disposal fees.

We operate a state-of-the-art facility dedicated to the production of high-strength needle-punched media. Our R&D team focuses on fiber density optimization and washability durability, ensuring our filters maintain their structural integrity and G4 efficiency even after multiple cleaning cycles.Quality is our lifeline. Every batch of washable pocket filters undergoes rigorous tensile strength tests and pressure drop analysis. We ensure our products can withstand 80% humidity and high-velocity airflow, adhering to ISO 9001 and international filtration standards to guarantee 100% reliability.

Frequently Asked Questions
Q1: How many times can the needle-punched media be washed and reused?
A: Depending on the dust type and cleaning method, our filters can typically undergo 3 to 5 cleaning cycles without compromising G3/G4 efficiency. We recommend using low-pressure air or water rinsing to maintain the fiber density.
Q2: Will washing the filter affect its filtration efficiency?
A: Our high-density needle-punched fabric is mechanically interlocked, meaning it doesn’t rely on chemical binders that wash away. This ensures stable G4 performance and consistent airflow even after washing, provided the media is fully dried before re-installation.
Q3: Is this filter suitable for environments with high humidity?
A: Yes. It is specifically designed to operate in up to 80% maximum humidity. The synthetic fibers do not absorb moisture, preventing the “sagging” effect and maintaining low drag efficiency in humid industrial climates.
Q4: How do I know when it’s time to wash or replace the filter?
A: We recommend cleaning the filter once the pressure drop reaches twice the initial resistance (approx. 140-160Pa). If the media shows signs of fiber fraying or if the resistance remains high after cleaning, it is time for a sustainable replacement.
Q5: Can I customize the media color for my specific system requirements?
A: Absolutely. We offer a variety of color-coded media, including White/Green, White/Blue, and pure White. These colors often help maintenance teams visually distinguish between different filtration stages or air intake vs. exhaust units.
