AR 45 Series 4590 is the Annovi Reverberi hot water high pressure washer complete with professional accessories, able to shift the most stubborn, troublesome dirt including oil and grease. It is a semi-professional model, suitable for DIY experts who demand the best and for professionals themselves.

It contains a pump with oil-immersed connecting rod system and brass head, complete with automatic by-pass valve for pump head pressure shut-off.

The single-phase induction electric motor with overload cutout delivers power of up to 2.5 kW, with a maximum flow rate of 500 l/h and maximum pressure of 150 bar.

To heat the water to up to 90°, the high pressure washer is fitted with a vertical boiler with double heating coil and refractory compound base, directly fuelled by the 4 litre diesel fuel tank; there is also a safety pressure switch to shut down the boiler in the absence of water.

Featuring the Total Stop System, the high pressure washer shuts down totally from remote when the gun trigger is released and reactivates when the user starts work again, to prevent overheating, extend high pressure washer lifetime and save water and money.

The 45 Series 4590 model also has an inspectable water intake filter and a diesel fuel inlet filter. A switch on the side of the high pressure washer selects hot or cold operation, with no temperature regulation function.

Its classical design guarantees convenience and agility, making the high pressure washer much easier to move around.

Equipped with a very handy accessories holder for stowing tools once the job is done, a large, ergonomic handle and two large rubber wheels, the high pressure washer is an excellent product with many useful functions, convenient and easy to use both in the home and at work, such as on small construction sites, on farms and in artisan workshops.

The professional accessories supplied with the 45 Series 4590 high pressure washer are: trigger gun, lance with fixed head without nozzle (56 cm), reinforced high pressure hose (8 m), ¼ MEG nozzle, and high pressure foam lance bottle kit.
