GUANLIN frameless pleated air filter, low resistance panel element for compact HVAC and equipment intake filtration.
Frameless pleated panel elements that maximise media area per unit volume, for compact HVAC housings and equipment intake filtration where frame thickness steals usable space.
Description
Removing the frame sounds like a cost reduction, and sometimes it is — but the real benefit is space. A frameless pleat pack puts more media into the same slot, which means a lower face velocity and a lower pressure drop for the same airflow. That matters in compact units and equipment intakes where the blower has very little static pressure margin.
Why Choose GUANLIN Frameless Pleated Filters
- More media per slot — no frame thickness means more pleats in the same opening.
- Lower face velocity — gentler airflow across the media, so less dust re-entrainment.
- Low pressure drop — protects blowers with limited static pressure margin.
- Light weight — easier handling and lower shipping cost.
- Simple replacement — slides into existing slots and retainers.
- Custom sizes — cut to your opening.
Application Scenarios
Compact HVAC units
Where frame thickness would reduce media area, frameless packs deliver more filtration in the same slot.
Equipment and panel intake filtration
Protects electronics, compressors and blowers in tight enclosures.
Fan coil and split unit filters
Light, low resistance and easy to change.
Light industrial ventilation
Coarse to medium dust control at low cost.
Replacement market
Direct swap for frameless elements in OEM equipment.
Transport and mobile equipment
Light weight and vibration tolerance suit mobile installations.

FAQ
Q1. Is frameless weaker?
It relies on the housing for support; where the slot is rigid it performs the same or better.
Q2. Why lower pressure drop?
More media area in the same slot means lower face velocity.
Q3. Custom sizes?
Yes.
Q4. MOQ and lead time?
50 pcs, 10–20 days.
