The Jyntrel aluminum pre-filter is a washable, multi-layer metal mesh filter designed to capture coarse dust, lint, and debris in commercial HVAC, industrial ventilation, and process exhaust systems. It is typically installed as a first-stage filter ahead of finer filters, protecting them from larger particles and extending their service life. It suits facility engineers, HVAC contractors, and OEMs working with high-humidity, high-temperature, or corrosive environments where disposable filters would be impractical.
This pre-filter is built for the front line of the air path. As air enters an HVAC unit or ventilation duct, it first meets the aluminum mesh, which intercepts larger particles before they reach coils, fans, or downstream filters. The open metal structure presents a low initial resistance, helping to maintain design airflow and reduce fan energy. The all-metal construction tolerates high humidity and elevated temperatures, making it suitable for exhaust systems where organic or synthetic media might degrade. In coastal or industrial atmospheres, the aluminum or stainless steel frame resists corrosion, and the mesh can be washed with water and reused, which is useful in dusty or greasy airstreams where frequent cleaning is required.
Because the filter is available in 21 mm and 46 mm depths, it can be specified for standard filter racks or custom housings. The multi-layer expanded metal design creates a tortuous path that captures particles while maintaining a low pressure drop. This behavior is consistent across the face area, helping to avoid localized loading that can disrupt airflow balance. In systems with variable air volume, the low resistance of the pre-filter supports stable operation across a range of flow rates.
Jyntrel aluminum pre-filters are typically rated G2 to G4 according to EN 779, or MERV 1 to 8 under ASHRAE 52.2, depending on configuration. They are designed to capture particles larger than 5 μm, including dust, fibers, and hair. The multi-layer metal mesh provides high dust-holding capacity, which reduces the frequency of replacement or cleaning. The filter is flame-retardant and resistant to acid and alkali, and it can be washed repeatedly with water, supporting a service life of 1–2 years in many installations, with regular cleaning. These characteristics make it a practical choice for pre-filtration in demanding environments, where disposable media would need frequent replacement.
To recommend the right configuration, we ask for the following information: the device or system model, the required face dimensions and depth (or a drawing), the operating airflow rate or face velocity, the expected particulate load and any chemical exposure, the operating temperature and humidity range, and the required quantity. With these details, we can specify the number of mesh layers, frame material (aluminum, stainless steel, or ABS), and whether a handle or other options are needed. Custom sizes are available; we can manufacture to any length, width, and thickness, and we support OEM/ODM projects including logo and packaging customisation.

These pre-filters are used in commercial HVAC systems, fresh air units, and cooling towers to protect coils and downstream filters. In industrial settings, they serve in high-humidity or high-temperature exhaust streams, such as those found in food processing, chemical plants, and metalworking facilities. They are also used as inlet filters for electronic equipment cooling and as pre-filters for HEPA systems in cleanrooms and data centers. In energy storage and semiconductor manufacturing, they help maintain air quality by capturing coarse particles before they reach more sensitive filtration stages. The washable nature of the filter is particularly valued in kitchen exhaust and oil smoke applications, where grease and fumes can quickly clog disposable media.
Jyntrel operates multiple automated production lines with a monthly capacity of several million pieces, supported by more than 20 years of export experience to Europe, the US, Japan, and South Korea. Our 50,000 m² plant includes six cleanrooms totaling 20,000 m². The in-house CNAS-accredited laboratory can issue test reports for filtration efficiency, dust-holding capacity, and resistance, and our quality management system is certified to ISO 9001, ISO 14001, and ISO 45001, with IATF 16949 added in 2024. Products comply with REACH and RoHS, and we can provide supporting documentation. From IQC to OQC, every batch is checked for consistency.

Jyntrel aluminum pre-filters are typically rated G2 to G4 under EN 779 or MERV 1 to 8 under ASHRAE 52.2, depending on the configuration. They are designed to capture particles larger than 5 μm, such as dust, fibers, and hair. The exact rating can be customised to your application.
The open metal mesh structure provides low initial resistance, allowing the filter to operate effectively at higher face velocities common in industrial ventilation. However, we recommend sharing your actual airflow and face velocity so we can confirm the appropriate mesh layer count and frame depth. In most HVAC applications, the filter maintains stable performance across a range of flow rates.
To quote accurately, we need the design airflow rate or face velocity, the required face dimensions and depth, and the expected operating temperature and humidity. If you have a system drawing or filter rack dimensions, that also helps. Please also indicate the contaminant type and concentration if known.
Yes, we support full customisation. We can manufacture to any length, width, and thickness, and offer aluminum, stainless steel, or ABS frames. The number of mesh layers can also be specified. Provide a drawing or sample and we will match it.
For standard sizes, the MOQ is typically 500–1,000 pieces; custom sizes have a negotiable MOQ. Standard stock items ship in 7–10 days, while custom orders generally take 25–35 days depending on quantity and complexity. Our 50,000 m² plant and multiple lines support large volumes.
Yes, we welcome sample evaluation. Standard size samples are free (you cover freight); custom samples may incur a fee that is refundable upon bulk order. Sample lead time is 3–7 working days. Our CNAS lab can also provide performance test reports.
Under normal commercial HVAC conditions, cleaning is recommended every 3–6 months, depending on dust load. The filter can be washed with water and reused multiple times, with an overall service life of 1–2 years. In heavy dust or grease environments, more frequent cleaning may be needed.
