Filtro de aire y filtración química
Pre-filtro pre-filtro por
A wire-supported pleated panel that increases coarse-media area and dust capacity without increasing the face size of the filter track.
- Expanded Media Area
- Wire-Stabilized Pleats
- Moisture-Resistant Frame
- Standard Filter-Track Sizes
Introducción del producto
The pleated pre-filter forms cotton-synthetic or fully synthetic media into evenly spaced radial pleats over a corrosion-resistant downstream wire grid. The pleat geometry adds media area and dust storage within a familiar panel footprint. Adhesive bonds between the media, support grid and enclosing frame stop pleats from collapsing or fluttering at high airflow. Standard 25, 50 and 100 mm nominal depths allow the filter to replace flat throwaway panels while providing a longer service interval.
Características clave
A corrosion-resistant expanded-wire backing prevents pleat collapse and media oscillation.
Diagonal frame members protect pleat geometry during transport and filter changes.
Multiple nominal depths balance available track space, resistance and dust-holding capacity.
Preocupaciones del producto del cliente
Pleated prefilters perform best when pleat spacing remains open and the panel seals evenly against the filter rack.
Flat pads require replacement before their full face area has stored much dust.The pleated pack multiplies usable media area and distributes deposited particles across deeper folds.
Closely packed pleats touch each other and create high-resistance dead zones.Controlled radial spacing keeps adjacent pleat walls separated throughout the panel.
Fan starts pull unsupported media downstream and permanently distort the pack.A bonded expanded-wire grid stabilizes the media on the air-exit side.
Humid intake air softens ordinary frames and opens bypass gaps at the corners.A high wet-strength frame with bonded mitered corners retains shape in normal HVAC humidity.
