Tunnel Ventilation

DACS MagFan Tunnel Ventilation

Ventilation is a key feature of effective agrihousing. Ensuring that air movement can exist promotes livestock productivity through the introduction of fresh air and the removal of moisture and odours resulting in overall improved air quality.

One of the best and most innovative agricultural fans on the market boasting aerodynamics and efficiency is the MagFan by DACS.

The MagFan quite simply is the most efficient wall fan on the world market. In a direct comparison against leading suppliers on the market today, MagFan offers at least 50% lower energy consumption at equivalent flow rates. View a recent case study here where it shows a saving of 75% on electricity.

MagFan is perfect for agricultural applications:

Simple to install and easy to run – the MagFan has a simplistic design and rugged construction

Reduces your energy bill with 70% compared to top ten competitors

Maintenance free – all components are either high grade plastics or stainless steel

Runs on 95% of the world´s power grid

Run on any voltage from 85 to 460V/50 or 60Hz

Motor (1.2 kW (1.6 hp)) is fully speed adjustable from idle to 660 rpm

Reduces CO2 emissions by at least two thirds

100% recyclable

Stackable components – means safe, ultra-compact shipping

Approximately 80% of the efficiency gain come from the advanced aerodynamics, and the impeller design in particular contributes significantly to the extreme efficiency of the MagFan. As a result of the advanced aerodynamics, MagFan is about three times as efficient as conventional wall fans on a yearly average.

Technical Features

Power

The direct drive 56” MagFan is powerful enough to run continuously at static pressures exceeding 80 Pascal (0.32”) and will output well over 72.000 m³/h (42,377 cfm) at neutral pressure, but still consuming only about one third of the power compared to similar size high-end fans.

Built in Variable Speed Drive

MagFan uses a Dedicated Variable Speed Drive with SoftStart. Your MagFan starts slowly and quietly and accelerates to the requested speed which can be defined either by a chosen fixed speed setting or run infinitely adjustable using the integrated variable speed setting. When running in the variable speed mode, the fan delivers exactly the required amount of air and the precise airflow control potentially offers savings in excess of 90% over conventional high-end fans.

The direct drive and the in-built loss free speed control features bring you the exact air exchange required, and the advanced impeller will deliver plenty of thrust and airflow at high RPM and gentle air exchange and phenomenal savings at lower speed settings.
