Modern and Precise Medical Device Wet Technology
The SPR4 unit is equipped with the fine hadewe nebulisation technology, that allows working with spray liquids without alcohol additive (e.g. just with distilled water and our AquaHy concentrate). That protects the patient and especially the user in long hours of continuous work. The speed of the modern brushless motor can be variably adjusted up to 40.000 rpm, and is shown in the unit’s digital display.
There are a couple of important functions to increase this spray unit’s value for the user. The first is a rinsing function with which a strong stream of water is used to rinse off the remains of skin and nails. The second is a drying function, where air is used to dry the spot of a recent treatment. Similarly, an automatic cleaning function is used to prevent blockage in the spray nozzle.
Handpiece and spray can be switched on and off (separately or both) with an optional foot switch. The SPR4 has a soothing blue light on the display and at the water tank. The unit is certified as a class 2A EU-Medical Device unit, and is our lower cost alternative of a spray drill for the professional, medical podiatry field.

Finest Spray Atomisation
You will be amazed at the atomising technology from hadewe, which allows for the finest spray mist on the market. Our specialised spray nozzle makes it possible to work with just demineralised (purified) water without alcoholic supplements, which is better for podiatrist and patient. The skin layers are also not attacked as much as they are with alcohol. Our own spray supplement AquaHy can instead be used to kill germs and is odorless.
Power Clamping System
The handpiece is equipped with a unique, patented clamping system. A chuck will open inside the handpiece by pressing the well-known hadewe knob forward. The instrument can now be entered into the unit without any resistance. This is especially important with smaller, sharp edged tools, since they can cause injury, if you need too much force to enter an instrument.
Pushing the knob back again will close the chuck, and the tool will be held very secure, even at high speeds. The tight grip also ensures the low-vibration running of the handpiece for which hadewe is famous. Conventional clamping systems with automatic clamping work with a mechanism in which rolls inside the handpiece wedge the instrument under pressure. At these systems it is not possible to enter the instrument without resistance. The handpieces with automatic clamping are also more sensitive to small deviations of tool tolerances. This will lead to higher vibration and poor holding force. That’s why the power clamping system is superior in many ways.
