G4 Pureflow Dust Prefilter

The KALTERMANN KM12 air cooler is equipped with an integrated antibacterial UV lamp , which adds an extra level of protection for the health of the environment.
This technology disinfects water and air , eliminating bacteria, viruses, fungi, and mold , ensuring a healthier and safer environment. Ultraviolet light works by destroying the genetic material of microorganisms, preventing their proliferation and improving the quality of the air released into the environment.
Particularly suitable for industrial environments or work areas, this system guarantees cleaner air , protection of workers' health and a safe and efficient working environment .

The KALTERMANN KM12 cooler uses an evaporative cooling system. Warm air is drawn into the unit and passed through a damp pad, which naturally lowers its temperature.
Unlike traditional systems, it does not use chemical refrigerants , offering an ecological, sustainable and low environmental impact solution .
By exploiting the natural process of water evaporation, the device releases a flow of fresh, pleasant air into the room, improving comfort in an efficient and natural way.
The KALTERMANN KM12 cooler is designed for Plug and Play installation , meaning it's ready to use without the need for complicated assembly or additional wiring. Simply plug it into the power supply and the device is immediately operational, making installation quick and easy, even for those with no technical experience.
The water tank can be filled manually or connected to the water mains for unlimited autonomy.
The filter can be easily inspected and replaced in just a few steps.



Pureflow filtration technology features patented filtration and purification technology that significantly improves the performance and lifespan of mobile adiabatic coolers even in environments with high dust concentrations .
This Kaltermann KM12 cooler has a G4 filter which guarantees 90% efficiency on 100 μm particles .

Pureflow with G4 filter is specially designed for use in dusty environments with high levels of impurities in the air.
It ensures the protection of the cooling system by protecting it from dust and increasing its performance and durability over time .

The G4 pre-filter is designed to provide effective protection against dust and impurities in the air. Classified as ISO Coarse , this filter is capable of blocking particles larger than 100 μm .
Strategically positioned at the system entrance, it prevents impurities from entering the cooler, thus ensuring greater efficiency , performance and long life of the appliance.
Perfect for industrial environments and dusty work areas , improving operator health and safety .

The KALTERMANN KM12 is an industrial cooler for large spaces that offers high performance with a maximum air flow of 12,000 m³/h , supported by a power of 440 W and a single-phase power supply . This cooler is equipped with a ½-inch water connection , allowing for automatic or manual power supply. Its compact size and weight of 43 kg make the KM12 easily transportable.
The air speed is adjustable to 3 levels , with the option to activate the oscillation mode for even distribution. It also includes a timer function for automatic on and off , improving energy savings. The KM12 is a silent device ( noise emission between 54 and 63 dB ), economical and environmentally friendly.
Its tank capacity is 70 L, with a water consumption of approximately 8-10 L/h .

NB to obtain the greatest possible efficiency of the cooler it is important that the room is adequately ventilated

KALTERMANN offers a 5-year warranty , with the exception of consumable parts such as the UV lamp and filter.
The KM12 is an evaporative cooler capable of rapidly lowering temperatures, improving worker comfort. It can be positioned wherever good ventilation is required, eliminating the need for traditional air conditioning, which is often impractical in open or very large spaces.
In industrial environments, where dust can be a problem, the G4 pre-filter helps keep the air clean, protecting machinery and improving worker comfort.
KALTERMANN evaporative coolers are also useful in environments where materials are stored or work is carried out on vehicles, as they can reduce heat without compromising air quality.
Its mobility and ease of installation make the KM12 particularly suitable for cooling temporary spaces, such as trade fairs and outdoor events, where climate management is a priority.
In these environments, temperatures can become high, so a cooler like the KM12 allows you to reduce heat naturally, protecting crops and improving agricultural work.
These coolers can also be used in more sensitive environments, such as livestock farms. In these cases, the coolers should be positioned at the entrance to the barn to ensure that the incoming air is not contaminated by internal dirt.

KALTERMANN supports companies with simple, sustainable solutions designed to improve employee comfort and safety while increasing productivity. As air treatment experts , we offer cooling solutions adapted to extreme heat thanks to mobile adiabatic chillers equipped with a patented purification system and manufactured in France .




The Kaltermann KM cooler can be equipped with a metal filter. This filter is specifically designed for use in particularly dusty areas, such as workshops with oily clouds and dusty environments such as carpentry shops, stoneworkers, and the like.
