Product Introduction
Perforated metal filter is made by punching regular holes on metal sheets and further processed into tubes, discs, panels or other filter shapes. It works as a simple and sturdy filter element to block solid particles from gas or liquid flow. This filter is widely matched with all kinds of industrial machinery for impurity interception and protection of core equipment.

Properties
Good structural rigidity, stable hole size, wear resistance, corrosion resistance, high temperature resistance, easy forming and machining.
Features
1. Various hole patterns available to fit different filtration accuracy
2. Solid plate structure, not easy to break under medium impact
3. Can be cut, bent, rolled and welded into many custom shapes
4. Smooth surface, convenient for cleaning and repeated use
5. Stable opening rate, consistent flow performance
6. Low cost compared with other precision filter elements
Application Scenarios
Industrial machinery protection: air compressors, hydraulic stations, pumps, fans, vacuum equipment inlet filtration
Water treatment: pipeline pre-filter, tank internal baffle filter, water tank impurity interception
Chemical industry: low precision liquid filtration, gas dust removal, material separation
Food processing: raw material screening, waste residue filtration
Agricultural equipment: irrigation filter, grain cleaning machine
Dust collection: dust cabinet, ventilation and exhaust system
Other fields: construction noise reduction, mechanical isolation, oil filtration
Product & Company Advantages (Anping Haopeng Metal Wire Mesh Co., Ltd.)
We are a local manufacturer in Anping, the wire mesh base of China. We finish punching, cutting, bending, rolling, welding and surface treatment in our own workshop.
We can adjust hole size, hole layout and opening rate following your machinery drawing and working condition. Small trial orders and bulk orders are both acceptable.
We check hole size, plate flatness and welding quality before shipment to avoid defective goods.
We provide practical selection advice for different machinery working environments. Our delivery schedule is reliable, and we can arrange priority production for urgent orders.
We support third-party inspection if required, and our perforated metal filters are supplied to many machinery manufacturers.
Customer Feedback
Most machinery manufacturers tell us our perforated filters keep consistent hole size and do not deform easily under continuous air or liquid impact.
Customers who use these filters for hydraulic systems mention that they effectively block large impurities and protect pumps and valves well.
Buyers for standard filter discs say we can quickly process custom sizes and the finished parts fit their machine mounts perfectly.
Users working in slightly corrosive environments are satisfied with the service life of our 316L and galvanized perforated filters.
FAQ
Q1: Can you make non-standard perforated filters according to our drawings?
A1: Yes. We produce custom shapes, hole specifications and sizes based on your drawings or samples.
Q2: Which material is suitable for hydraulic oil filtration?
A2: 304 stainless steel is the common choice. If the oil contains corrosive additives, 316L stainless steel is recommended.
Q3: What is the maximum working temperature the perforated metal filter can bear?
A3: It mainly depends on the material. Carbon steel and stainless steel can adapt to most normal and medium-high temperature working conditions. We will confirm the suitable material after you provide working temperature.
Q4: Can I get samples for machine test?
A4: Samples are available. Sample cost and freight will be discussed separately.
Q5: How to clean perforated metal filters?
A5: Use high-pressure water or compressed air for back flushing. Stubborn dirt can be cleaned by ultrasonic washing. Avoid grinding the hole surface roughly.
Q6: What is your production lead time?
A6: Simple regular products can be delivered fast. Custom perforated filters usually take 15-20 days, decided by quantity and processing difficulty.
