GUANLIN equipment intake air filter, frameless pleated element for compressors, blowers and control cabinets.
Frameless pleated intake elements protecting compressors, blowers, generators and electrical cabinets from dust ingress where frame depth steals usable space.
Description
Dust ingress is the quiet killer of rotating equipment. A compressor that breathes grit loses impeller efficiency within months; a control cabinet that fills with conductive dust fails at the worst moment. Intake filtration is cheap insurance, but it only works if the element fits — which is why frameless pleated elements matter in equipment where every millimetre of depth is already allocated.
Why Choose GUANLIN Equipment Intake Filters
- Frameless design — more media in a shallow intake slot.
- Low pressure drop — does not starve the machine of air.
- G3/G4 efficiency — stops the coarse fraction that does the damage.
- Light weight — no vibration fatigue in mobile equipment.
- Simple replacement — slides into existing retainers.
- Custom sizes — cut to the intake opening.

FAQ
Q1. Why frameless?
More media in a shallow intake slot where frame depth is not available.
Q2. Will it restrict airflow?
No — the larger media area keeps resistance lower than a framed panel.
Q3. How often to change?
Check monthly; replace when visibly loaded.
Q4. MOQ and lead time?
50 pcs, 10–20 days.
