HARDI mistblowers lets you spray without compromise – all your different crops. Whatever you grow – from small bushes to large tree plantations.

Robust and simplicity
Benefit from the expertise gained with HARDI’s many years of worldwide experience in orchard spraying. Everything from tank design and built to the latest electronic control systems is reflected in our sprayers.


The OP15 as well as OP35 and OP55 are same application technology in the entire OPTIMUS application family. It is based on the same spraying devide in hydro pneumatic as well as in pneumatic applications. The main difference between OP15, OP35 and OP55 is the air supply drop leg that drives the droplet to the targeted plant.

Air kits & deflectors

The Air Kits offer better air distribution, higher airflow, a lower noise level, and less power consumption - all together to provide you with a first-class application. 

The fan housing is made of high-impact polyethylene and incorporates a unique channel plate that makes the air production much more uniform. The fan blades are made of polymer, a very strong synthetic material, and can be adjusted in order to adapt the air volume to the individual orchard.

The air kits are fitted with double, non-drip nozzle holders.

HARDI’s special deflectors help you optimize and adapt the generated air to your specific crop and working conditions.
