Continuous building ventilation provides high indoor air quality, and the design ensures that all building process or extracts operate to a maximum efficiency while still maintaining a positive building pressure.

The Econo-Air 3000R series is designed for buildings with varying extract loads such as warehouses, loading areas, gymnasiums, and sports halls. The 3000S series is suitable for cinemas, swimming pools, nightclubs, bus depots, and heavy industrial use. The 3000E series is suitable for emergency smoke and/or exhaust ventilation.

The Econo-Air 3000 incorporates leading edge fully modulating ‘Rapidnet’ microprocessor technology temperature controls. Combined with a high efficiency burner, intelligent controls, and the effect of slightly positively pressurising the building, the system ensures extremely even temperature distribution through the heated area of the building.

The system also incorporates fully modulating, automatic re-circulation and variable air-mixing. With the added advantage of continuous building ventilation during the heating season and ‘free cooling’ during the summer months, the system offers considerable energy savings over conventional heating systems.

Stokvis also offers the smaller Econo-Air 1000C series, which is suitable for churches, public houses, restaurants, cinemas, nightclubs, village halls and community centres.
