A compact Energy Recovery Ventilator designed to bring fresh outdoor air into the room, filter incoming air, support indoor air purification and exhaust stale indoor air. A practical solution for separate spaces with controlled ventilation.
Fresh air for separate spaces.
Unlike a standard air purifier that mainly filters and recirculates indoor air, an ERV is designed around air exchange: outdoor air is introduced into the room while indoor air is exhausted outside.
The supplied PAQOS / Delta wall-mount material identifies the VEB100ATH-W as a compact wall-mounted ERV intended for individual rooms and living spaces.
Filter the air. Protect the space.
The supplied wall-mount material documents a two-stage high-efficiency filtration arrangement built around a pre-filter and HEPA filter. The design below also provides an activated-carbon tab to match the product presentation shown in your current page design.
Pre-Filter
The pre-filter acts as the initial filtration stage, capturing larger airborne particles and helping protect the downstream high-efficiency filter.
HEPA Filter
The supplied wall-mount material describes a HEPA stage for PM2.5, pollen, fine dust and dust mites. The catalogue states a 0.3 μm particle diameter and PM2.5 purification of 98% on the wall-mount model.
Activated Carbon Filter
Activated carbon is used on applicable filtration configurations to adsorb odours and selected airborne chemical compounds / VOCs. Confirm final filter configuration for the exact PAQOS wall-mount SKU before publishing it as a standard component.
Two-stage high-efficiency filtration.
Pre-filtration handles larger airborne particles, while the HEPA stage addresses much finer particles. The supplied material identifies 10 μm pre-filter filtration and 0.3 μm HEPA filtration.
The wall-mount catalogue states PM2.5 purification of 98% for the VEB100ATH-W configuration.
Air exchange. Purification.
The wall-mount design combines fresh-air intake, indoor-air exhaust and indoor purification in one compact wall-mounted solution.
Monitor the air. Control the system.
The supplied Delta control material describes monitoring of indoor PM2.5, CO₂, temperature and humidity, together with automatic operation, scheduling and integration capabilities on supported controller configurations.
