Pureflow G4 Dust Pre-filter

The KALTERMANN KM12 cooler is equipped with an integrated antibacterial UV lamp, which adds an extra layer of protection for the health of the environment.
This technology disinfects water and air, eliminating bacteria, viruses, fungi, and molds, 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 worker health, and a safe and efficient working environment.

The KALTERMANN KM12 cooler uses an evaporative cooling system. Warm air is drawn into the device and passed through a wet panel, which naturally lowers its temperature.
Unlike traditional systems, it does not use chemical refrigerants, offering an ecological, sustainable, and low environmental impact solution.
By harnessing the natural process of water evaporation, the device releases a flow of fresh and pleasant air into the environment, improving comfort efficiently and naturally.
The KALTERMANN KM12 cooler is designed with Plug and Play installation, meaning it is ready to use without the need for complicated assembly or additional systems. Simply connect it to the power outlet, and the device is immediately operational, making installation quick, simple, and suitable even for those without technical experience.
The water tank can be filled manually or connected to the water mains for unlimited autonomy.
The filter is easily inspectable and replaceable in a few steps independently.



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

Pureflow with G4 filter is specifically designed for use in dusty environments with a high level of airborne impurities.
It ensures the protection of the cooling system by shielding it from dust and increasing its performance and durability over time.

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

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

N.B. To achieve the highest possible efficiency from the cooler, it is important that the environment is adequately ventilated
KM12 is an evaporative cooler capable of rapidly lowering temperatures, improving operator well-being. It can be positioned where good ventilation is required without resorting to traditional air conditioners, which are 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 vehicles are worked on, as they can reduce heat without compromising air quality.
The mobility and ease of installation make the KM12 particularly suitable for cooling temporary spaces, such as fairs and outdoor events, where climate management is a priority.
In these environments, temperatures can become high, so a cooler like the KM12 allows for natural heat reduction, 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 of the barn to ensure that the incoming air is not contaminated by internal dirt.




It is possible to choose to equip the Kaltermann KM cooler with a metal filter. This filter is specifically designed for use in particularly dusty areas, such as workshops with oily mists and environments with a high presence of dust, like woodworking shops, stone processing, and similar.

This Kaltermann product is covered by an extended 5-year warranty.
Please note that consumables like UV lamps and filters are excluded from the warranty.
