[INQ. NO. 2507M10] Motor Seven Co., Ltd.is a reliable Korean B2B supplier of auto parts with a strong reputation in the global market.
Motor Seven works with both OEM and aftermarket products, offering a wide range of parts — from filters and turbochargers, to suspension components, and electronics. It holds international certifications and operates overseas manufacturing facilities, while maintaining a stable and well-established export network.

Water Pump
Water pumps produced by Motor Seven are a crucial component of a car’s cooling system. It circulates coolant from the radiator through the engine and back, helping to regulate engine temperature. It is typically mounted on the engine block, and driven by the timing belt, serpentine belt, or chain.

Brake Pads
Brake pads produced by Motor Seven are a key component of the disc-braking system in vehicles. Brake pads create friction against the brake disc (rotor) when the brakes are applied. This friction slows down and eventually stops the vehicle.

Filter
Filters produced by Motor Seven are essential for maintaining engine health, cabin air quality, and fuel-system efficiency.
Motor Seven’s automotive filters are: Oil filters (to remove contaminants from engine oil); air filters (to remove dust and debris from air entering the engine); and cabin air filters (to clean air entering the cabin).
Motor Seven has established itself as a trusted partner in the global automotive parts market.
Since 1998, Motor Seven has been providing the best products and services based on quality and innovation.
Currently, Motor Seven is supplying automotive parts worldwide and is building trust with customers.
“We are prioritizing customer satisfaction through superior technology and stringent quality control. Our goal is to meet and exceed our customers’ expectations. As a responsible company, we are committed to sustainable growth and environmental management,” remarked the company’s CEO.

[INQ. NO. 2307E03] K-1 EcoTech Co., Ltd. was established in 2006, and its main business areas are swimming pool facility maintenance management, manufacture and sales of water-purification devices, and operation & management of swimming pool facilities.


K-1 EcoTech is selling tubular pre-coated filters designated as innovative products by Korea’s Public Procurement Service, which are products applied with water-treatment technologies certified by the International Swimming Federation (FINA). As its next project, the company is developing and commercializing specialized filters for water quality improvement in water tanks in apartment houses.


In addition, K-1 EcoTech acquired new marine technologies in order to supply seawater farms, and is expanding its business area by applying its products to seawater.

Performing high-filtration linear velocity
The tubular pre-coated filter (K-TTF) requires a compact installation area (approximately 1/4 of its existing technology), compared to the conventional pressurized filters and horizontal pressure & multi-layer composite filters. It is an excellent product that provides filtration linear velocity of 5 to 6.25 m/hr.


In order to improve filtration performance, the filter medium is coated in advance – and after the filter operation is performed, the contaminants and the filter medium on the surface of the filter tube are removed through desorption, and the filter operation is performed again. The filter medium has the advantage of being reusable.


In addition, if the filtration efficiency is not recovered through the desorption process, the filtration efficiency can be recovered through backwashing, which is excellent in terms of management efficiency, as it takes just 10 minutes once per week.

WiFi Filter

https://korean-machinery.com///inquiry

[INQ. NO. 2211M27] WIDU’s WiFi Filter is short for Wide Fiber Filter, which is “pull/rotation fiber filtering equipment” used to improve the water quality of purification facilities, sewage treatment plants, wastewater plants and re-circulated filteration facilities by utilizing the fiber filter media with activated carbon added inside the strainer.


To get the equipment started, the fiber filter media inside the strainer is pulled up and rotated, to control the pores and subsequent filtration, and then the backwash processes are repeated automatically.


When proceeding with filtration, the fiber filter media is compressed to shrink the size of the pores in a way of filtering out the suspended solids in the raw water. When reaching the set pressure and time, the backwash is started to wash out the suspended solids that are attached to the fiber filter media by using backwash water and air.


The use of the fiber filer media that is embedded with activated carbon is also able to remove simple suspended solids and improve not only turbidity, but also some colors.


Depending on the changes in the filling rate of the filter media and thickness of the fiber, the efficiency of the filtration and backwash can be enhanced.


As the backwash air chamber is placed inside the strainer, it is possible to blow the backwash air out evenly.
When proceeding with the backwashing process, the backwash air from the bottom of the fiber filter media is evenly emitted, resulting in enhancing the efficiency of the backwashing process.


By adding variety to the pores of the filter media through compression and relaxation processes when doing the filtration and backwash, the efficiency of the filtration and backwash is outstanding.


The filtering equipment can be manufactured in both compression and gravity types.


The filtering equipment is excellent in terms of performance and it is simple to do the backwash with only a small amount of backwash water needed. In addition, the filling rate of the fiber filter media can be adjusted and the filter media can be manufactured and replaced with ease.


Thanks to the simple internal structure, the equipment is easy to maintain and is effective in reducing costs as it needs only a minimum area for its installation.
