Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer with over 25 years of expertise in wire mesh and filtration solutions. Our Vacuum Conveying Filter Element for Pneumatic Conveyors, featuring a 3-Layer Sintered Mesh and 5 Micron filtration rating, is designed to deliver exceptional performance in demanding conveying applications. Compliant with ISO 16890 standards, this filter element ensures reliable particle separation, extended service life, and minimal downtime – directly supporting your production efficiency.
Engineered with precision, our sintered mesh filter element combines three layers of stainless steel wire mesh into a single, robust structure. The outer layers provide mechanical strength and uniform flow distribution, while the middle layer captures fine particles down to 5 microns. This design eliminates the need for multiple filter stages, reduces pressure drop, and allows for easy backwashing or ultrasonic cleaning. Whether your system handles powders, granules, or bulk solids, this filter element maintains consistent performance under varying vacuum conditions.
Below is a summary of key technical specifications:
| Parameter | Value |
| Filtration Efficiency | 99.9% for particles ≥5 μm |
| Operating Temperature | -20°C to 400°C (customizable) |
| Maximum Differential Pressure | 0.5 MPa (optional) |
| Material Options | 304, 316L, Hastelloy (upon request) |
| Standard Compliance | ISO 16890 |
| Cleaning Method | Backwash, Ultrasonic, or Chemical |
Key Features & Benefits
- 3-Layer Sintered Mesh Structure – Provides high mechanical strength and uniform filtration without media migration. The sintered bond eliminates fiber shedding, ensuring clean product discharge.
- 5 Micron Filtration – Captures fine dust and contaminants effectively, protecting downstream equipment (valves, blowers) and maintaining product purity.
- Low Initial Pressure Drop – The open mesh design minimizes resistance, reducing energy consumption of vacuum pumps.
- Reusable & Washable – Can be backwashed in place or removed for ultrasonic cleaning, extending service life compared to disposable filters.
- ISO 16890 Compliant – Tested according to international standards for general ventilation filtration, ensuring consistent quality and performance.
- Customizable Dimensions – Available in various diameters, lengths, and end cap configurations (open, closed, gasket, etc.) to fit existing filter housings.
- Wide Material Compatibility – Standard stainless steel 304/316L handles most powders; superalloys available for corrosive or high-temperature environments.
Our filter elements are ideal for pneumatic conveying systems handling cement, plastics, chemicals, food ingredients, pharmaceuticals, and minerals. The robust construction withstands the abrasive nature of many materials, and the smooth surface prevents material build-up. In vacuum applications, the element maintains structural integrity even under rapid pressure fluctuations.
We understand that every conveying system is unique. Our engineering team can modify the filter element’s active area, connection type, and micron rating to match your specific requirements. Lead times are fast, and we offer OEM/ODM services.

Frequently Asked Questions
Q1: How long does the filter element last?
A: Service life depends on operating conditions and cleaning frequency. With proper backwashing, the element can last 1–3 years or more in typical applications.
Q2: Can I clean the filter element without removing it?
A: Yes, in many systems the element can be backwashed in place using compressed air or liquid. We also recommend periodic ultrasonic cleaning for deep removal of embedded particles.
Q3: Are custom sizes available?
A: Absolutely. We can produce filter elements with custom diameters, lengths, end caps, and connection types. Please provide your housing dimensions or a drawing.
Q4: What is the difference between a sintered mesh filter and a standard mesh filter?
A: Sintered mesh is bonded by heat and pressure, creating a rigid, multi-layer structure that eliminates fiber shedding and has higher mechanical strength. It is more durable and suitable for backwashing.
Q5: Does ISO 16890 compliance affect the filter’s performance?
A: ISO 16890 is a test standard for general ventilation filters. Compliance ensures our filter elements are tested under consistent conditions, guaranteeing reliable efficiency and pressure drop data for your system design.
Q6: Can this filter element be used for food-grade applications?
A: Yes, when made from 316L stainless steel and with appropriate surface finishes, the element meets food contact requirements. Please specify your regulatory needs (e.g., FDA, EC 1935/2004) for a customized solution.
Q7: What is the maximum temperature this filter can withstand?
A: Standard stainless steel elements can operate up to 400°C. For higher temperatures, we can use superalloys like Inconel–please consult our technical team.
Q8: How do I choose the right micron rating?
A: The optimal micron rating depends on the particle size distribution of your material and the required product purity. A 5 micron element is suitable for fine powders; for coarser materials, we offer 10, 20, 50, or 100 micron options.
