Air Filters
Whalesens makes air filters for equipment as well as for buildings. The WSE-S range is open-cell polyurethane foam loaded with powdered activated carbon, cut to sheet or frame size, and it was developed for EV charging piles and outdoor cabinets where the filter has to stop dust and insects, survive rain and ultraviolet light, and still keep the pressure drop low enough for a small fan.
The media is washable and the frame and protective mesh are reusable, so one panel can serve several service cycles. Send us the enclosure opening, the airflow and what you need to stop — dust, oil mist or odour — and we will quote a pore size and thickness for it.
Selection table
| Model | Media | Pore size | Thickness | Carbon content | Initial resistance | Flame rating |
|---|---|---|---|---|---|---|
| Whalesens WSE-S EV Charging Air Filter | Ultra-Thin, Custom & Washable | Polyurethane open-cell foam | HR-20 (35 ppi), HR-15 (30 ppi), HR-10 (20 ppi) | 3 – 100 mm | ≥50% | ≤35 Pa (10 mm medium-pore media at 1.0 m/s) | UL94 HF-1, or UL900 on project request |
How it compares
Foam vs pleated media
A pleated panel packs more media area into the same face size, so it holds more dust and suits a ducted HVAC system with a proper holding frame. Open-cell foam is rigid, keeps its shape without a frame and can be washed, which is why it is used on equipment enclosures, vent panels and charging piles rather than inside ducts.
Carbon-loaded foam vs a separate carbon stage
In the WSE-S panels the activated carbon is carried inside the foam, so a single part does coarse dust and light odour duty. Where the gas load is real — solvents, ammonia, exhaust fumes — one panel is not enough and a dedicated carbon panel, carbon bag or V-bank carbon filter should be added downstream.
Washable vs disposable
Washable panels cost more per unit and less per year, but the efficiency you get back depends on the pad being refitted and seated properly. Disposable pleated panels are more consistent frame to frame and are the better choice where the maintenance team cannot guarantee a refit procedure.
Where it is used
EV charging piles and outdoor cabinets
Intake protection for DC fast chargers, AC piles and outdoor power cabinets, where dust, insects and humidity are the main causes of fan and electronics failure.
EV charging air filter case →Wind power and new energy
Nacelle, converter and control cabinet filtration on wind turbines and energy storage equipment, often as a washable panel on a service interval.
New energy filtration solutions →Marine and coastal installations
Engine rooms, switch rooms and deck equipment, where salt air and oil mist mean the filter has to be cleanable and corrosion resistant.
Marine equipment case →Electrical rooms and switchgear
High and low voltage switch rooms and control rooms, where the filter protects busbars and relays from conductive dust.
