The Oltaven Mini-Pleat Panel Filter is a no-partition medium efficiency filter that removes micron-sized particles from air in commercial HVAC, cleanroom pre-filtration, pharmaceutical, electronics and industrial applications. It is built with glass fibre or PTFE media, an anodised aluminium or stainless steel frame and hot-melt adhesive separators. It suits facility engineers, HVAC contractors and OEMs who need a compact, low-resistance filter that delivers consistent efficiency from M6 to E11. Oltaven manufactures the finished filter—not just the media—in Zhongshan, Guangdong, China.
A filter’s job is to hold particles while letting air through. The media does the holding, but the finished filter determines how well that media performs. In a mini-pleat panel, media is folded into tight pleats and held apart by beads of hot-melt adhesive instead of aluminium separators. This design packs a large media area into a shallow frame, so air moves slowly through the pleats, giving particles more chances to stick while keeping resistance low.
Oltaven buys glass fibre and PTFE media, then pleats, frames and seals it in-house. We sell finished filters, not just media. That means we control pleat depth, adhesive pattern, frame squareness and seal integrity—the four factors that decide whether a filter meets its rated efficiency and resistance in the field.
Efficiency, resistance and dust capacity are set by a chain of choices, not by media alone. The table below explains how each step in production shapes the final result.
Media grade. Finer fibres capture smaller particles but raise resistance. Oltaven offers glass fibre and PTFE media to cover M6 through E11, so you can match efficiency to the particles you need to remove.
Pleat geometry. Deeper pleats and more pleats per filter add media area, which lowers face velocity and resistance for a given airflow. The trade-off is depth: a 50 mm filter fits tight spaces, while a 70 mm filter adds media area and dust capacity.
Adhesive separators. Hot-melt beads hold pleats open and prevent them from collapsing under pressure. A consistent bead pattern keeps airflow even across the filter face and avoids bypass.
Frame and sealing. An anodised aluminium or stainless steel frame keeps the pleat pack rigid and square. Proper sealing between media and frame stops air from sneaking around the filter, which would lower overall efficiency.
Cleanroom assembly. Oltaven builds filters in six cleanrooms covering 20,000 m² of the 50,000 m² plant, reducing contamination during pleating, framing and sealing.
The mini-pleat panel filter is used wherever air needs medium-efficiency cleaning without high energy cost. Typical uses include:
In each case, the filter can run alone or as a pre-filter ahead of a higher-efficiency stage.

Custom projects follow a structured path from requirement to delivery:
To receive a tailored proposal, please tell us your device or vehicle model, required size or drawing, airflow or water flow, operating conditions and estimated quantity. Our engineering team will respond with a specification and quotation. Contact Oltaven to discuss your filter requirements.
Resistance depends on media grade, pleat geometry and adhesive pattern. A finer media or shallower pleats reduce airflow area, raising resistance. Oltaven balances these factors so each M6–E11 filter meets its rated airflow within the specified resistance range.
It starts with your requirements: device model, dimensions or drawing, airflow, operating conditions and quantity. Our team reviews them, proposes a media and frame combination, and provides a quotation and sample for validation. Bulk production follows sample approval.
The Oltaven Mini-Pleat Panel Filter covers M6 to E11, spanning medium to sub-high efficiency. Selection depends on the particles you need to capture and the resistance your system can accept. Our team can help match a grade to your application.
Yes. We offer non-standard sizes with 50 mm or 70 mm depth, and frame options include anodised aluminium and stainless steel. Customisation is supported by our 20,000 m² cleanroom and CNAS testing centre.
After reviewing your requirements, we provide a quotation and, if needed, a sample for testing. Sample and freight terms depend on the specification; please contact us to discuss your project.
MOQ depends on the specification and customisation. Please share your requirements so we can confirm the MOQ for your order.
Lead time varies with order size and customisation. Once your specification is confirmed, we will provide a production schedule.
Replacement interval depends on operating conditions, dust loading and airflow. Monitor pressure drop and replace the filter when it reaches the recommended final resistance or after the interval advised for your system.
