History
Gesner Sepehr Kaveh Company, under the brand GESNER, began its operations in 1999 with an official license from the Ministry of Industry and Mines. The company is active in producing various types of filters for heavy vehicles, industrial, power plant, refinery, and specialized applications, as well as different types of oil-bath air cleaners and housings
Over the past 11 years, this company has consistently utilized skilled personnel, high-quality raw materials, and modern European machinery and technology—particularly from Italy. By adhering to national standards, it has successfully produced more than 500 types of air filters, oil-bath air cleaners, and housings, contributing significantly to the country’s self-sufficiency in this industry.
High-Quality Product Manufacturing
We have placed the production of premium-quality products at affordable prices at the forefront of all our activities. To achieve this goal, we have taken comprehensive steps to carry out every stage of filter manufacturing — from mesh production, pressing, cutting, and electrostatic coating to electroplating and all other necessary processes.
Leading Manufacturer
Today, Qasner Filter is recognized not only as a manufacturer that performs all stages of filter production in-house, but also as an important supplier for other companies. Over the years, the company has continuously worked to share its valuable knowledge and expertise, successfully fostering several entities that now operate independently within this industry.
