The new DA 820 exhaust unit


DA 820 exhaust unit can exhaust 75% more air than DA 600

In June 2019, we launched the DA 820, an upscaled version of our best-selling DA 600 exhaust unit. The DA 820 can exhaust 75% more air than a DA 600 can, which has already made it a popular choice all over the world.

DA 820

  • Can exhaust 75% more air than DA 600
  • Fewer exhaust units needed
  • Fewer units to clean and maintain


One of our most recent installations is at Henrik Holm, a pig farmer in Thyholm, Denmark, who runs five finisher sections, each with twentyfour pens. Henrik was very pleased with the SKOV ventilation system installed in all his houses, so when facing an expansion in 2019, it was evident for him once again to reach out to SKOV. Whenever a ventilation system is requested from SKOV, our Projecting Department calculates the best suitable solution for the customer, based on several factors such as performance, price, and energy usage.


In Henrik’s case, it was evident that DA 820 was a perfect fit. Although the cost of one DA 820 is higher than one DA 600, the significantly increased m3 air exhausted per unit means that fewer units are needed, ultimately making it a cheaper solution for the customer. Fewer exhaust units with higher air capacity have many advantages, including:


- Decreased cost of freight and installation

- Less cabling

- Fewer units to clean and maintain

Bigger and better

With an inside diameter of 820 mm, the DA 820 can exhaust 75% more air than the DA 600 that has a diameter of 650 mm.


Like the DA 600, you can install the DA 820 as either a roof or wall outlet, depending on the optimal conditions for the system. All additional SKOV components for exhaust units have similarly been made available for the DA 820, including the drip tray, light bowl, and roof cap with a net to avoid ingress of birds.


The exhaust unit is of high quality, easy to maintain, and easy to install, which makes it a popular choice all over the world.


At SKOV, we aspire to continuously develop the best quality products, not only in terms of usage and capacity but also for energy level. The fan in DA 820 is efficient concerning energy consumption, and SKOV developed a new design for the fan blade, which enables the unit to exhaust the maximum amount of air while keeping the energy consumption low. Additionally, the DA 820 can operate SKOV's Dynamic MultiStep for even more energy-efficient performance.
