The portable electrical precipitator produced by AIRTECH 21 Co., Ltd. is a dust collector that can automatically diffuse the compressed air inside the cartridge filter to completely eliminate fine particles. The filters are easily removable without using a flynut. Its exclusive design realizes phenomenal wind volume and wind pressure as well as high efficiency and low noise.
Displaying the dust accumulation status on an analog or digital differential pressure gauge, it notifies the user when to replace the filter. The dust box installed on the bottom of the main body can be easily detached with one touch, allowing the user to re-collect dust and raw materials.
AIRTECH 21’s multi-purpose precipitator can be applied for various usages as it can collect different kinds of dusts, wet process, dry process, fume, gold and silver works, etc. It operates the motor stably by releasing oil and moist inhaled through the intake into the side section not passing the motor part. It can be easily assembled because internal and external covers are disassembled merely by opening a one-touch lever when cleaning.
Durability of the product has been increased by mechanical design, and with the practical structure, it has a competitive price compared to the capacity of other products. Damage to the turbo-type impeller is prevented by a detachable chip. It can be cleaned with the ceramic coated filter for a long time.
Currently, AIRTECH 21 is developing technologies such as high-efficiency filters, highly advanced precipitation methods, etc., and exports various products to different countries for the first time in Korea. Also, it retains patents, utility models, registration of design, CE certificates, ISO certificates, etc.
Various hazardous substances that are emitted from industrial sites are becoming a social issue because they pollute the environment and have a great impact on operators’ health. 
Based on its establishment philosophy, AIRTECH 21 has sought to constantly research and produce excellent precipitators and satisfy customers with differentiated service. As a result, it has become a competitive company among various companies already occupying the market.
AIRTECH 21 is committed to being a company that is reliable and creates new values through steady development of technologies and consistent management innovation. AIRTECH 21 is producing the best precipitators based on a philosophy of a clean and safe operational environment without harmful substances as the foundation for the health of individuals and social harmony.

highly stiffness disk coupling for machine tool. It has zero backlash.
DURIMITEC is aggressively responding to the swiftly changing part industry’s paradigm based on its sales strategies targeting not only for the domestic market but also for potential overseas markets.
CPS Mini Chain is widely used for automation production line and equipment. Cable chain is made of polyamide 6 with glass fiber that helps cable chain perform excellent durability in speedy operating environment. CPS Mini Chain can bear up to 15m/s² of operating conditions. Required operating condition is 6m/sec. There are four series of CPS Mini Chain and CPS030, 033 can be applied to long travel operating environments.
Shift Chain features excellent performance of unsupported length, with easy assembly and disassembly. This is a CPS’ best-selling type of cable chain. When customers especially take account of the factor of ‘unsupported length’, Shift Chain will be a right choice to be selected. There are ‘BR’ (Bending Radius) that determines shift chain’ value of bending radius. Shift Chain is widely used in various environments and it helps customers maintain stock of each part of the shift chain, which means that the shift chain has a simple structure for users to either assemble or disassemble by themselves.

Unity systems are an innovative integral solution by unifying cable chains and bracket supporters.
Korea Coupling manufactures various types of industrial couplings such as steel flex, rigid, flexible, and elastomeric couplings that are mainly used in hydraulic machineries, pumps, compressors, blower fans, conveyors, cranes, and thrusters as well as for general power driven industrial equipment.

Users need to set it up horizontally to control the water level. The connecting wire needs to be long enough for use. Users should have the water tank checked and cleaned periodically. If there is no humidification, users need to turn the power off and check the water level. If water overflows, operators need to turn the water tap off and check the float valve.

Weltem’s portable air conditioner features the so-called “spot cooling” for large areas where cooling of entire areas is impractical like factories, open areas, etc. These conditioners are much more economical to provide cool air to people or material directly, rather than entire cooling. This product also provides a “room-cooling” function for closed areas to control the temperature of the area.
