  • 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 situated outside the airstream.
  • HAROl's special deflectors help you optimize and adapt the generated air to your specific crop and working conditions.

Available in tank sizes 1000.1500. 2000. 8.3000 L.

The diaphragm pumps are designed for the application of plant protection products. The diaphragms separate the liquid from the vital parts of the pump such as its bearings and crankshaft ensuring reliable and durable operation.

HARDI diaphragm pump features: 

  • Self-priming
  • Able to run dry without damage
  • Grease-lubricated crankcase
  • Chemical resistant diaphragms and valves
  • Able to rotate clockwise or anti-clockwise
  • Easy to service without special tools

The chassis is made of special UPN steel profiles providing robust durability and resistance to vibrations. The design and construction prevent accumulation of dirt and thereby prevent corrosion.

The chassis is protected with a top of the line powder paint surface treatment which includes

  • Steel bullet grinding of all steel parts
  • Pretreatment tunnel with 4 different “showers” which removes possible grease and applys anti-oxidation such as zinc, phosphate acids and nano ceramic. 
    Parts enter the drying oven, and continue towards the painting line, where the powder is applied. 

  •  Parts enter a 200º oven to convert the applied powder to a top professional surface protection, which we also call powder paint.

  • All mistblowers are also built with DELTA TONE ® treated bolts and nuts, to give this small, but important, part of the machine a much needed anti-corrosion nuts and bolt.

Control unit
CB/2 & CB/4 control unit
The CB has electrical remote control of all functions and is available with 2 or 4 distribution valves. The pressure regulation valve is made of stainless steel for maximum resistance to aggressive products, and the rest of the vital parts are completely sealed off from the spray liquid. The C8 unit includes pressure equalization device and pressure gauge. Maximum working pressure is 20 bar. Can optionally be fitted with a

HAROI CONTROLLER. SV/2 control unit
Solenoid valves operate the SV control, it has two distributors that are remotely controlled. Manual pressure regulation. A HAROI CONTROLLER can be fitted as an option.
