About Our Company
Quality Verified Through Systematic Testing
Turn Filter’s dedicated R&D laboratory, established in 2014, serves as the verification center where products demonstrate their capabilities under controlled conditions simulating real-world use. We don’t just manufacture filters and hope they work properly—we systematically test every product design to measure actual performance against specifications, identify potential improvements, and verify that what we ship to customers will perform as promised when installed in vehicles and equipment. Our state-of-the-art testing facility houses specialized equipment for evaluating air, fuel, oil, and cabin filters according to recognized industry standards and protocols.
Quality at Turn Filter extends beyond final inspection to encompass systematic control throughout manufacturing processes, ensuring problems get caught and corrected before they become defective products. Our quality approach begins with incoming material verification, continues through production process checkpoints monitoring critical dimensions and assembly quality, and concludes with final product testing verifying completed filters meet all specifications before packaging and shipping. This comprehensive quality management delivers the batch-to-batch consistency businesses need for confident product specification and reliable customer satisfaction across every order.
R&D APPROACH
Innovation Through Systematic Development
Turn Filter’s research and development activities extend beyond just testing current products to include development work exploring potential improvements in filter performance, manufacturing efficiency, material sustainability, and cost competitiveness. Our laboratory provides testing capabilities that let us evaluate new filter media, trial different construction approaches, and measure whether proposed changes actually improve performance or just increase complexity without meaningful benefit.
Material Innovation
Continuous exploration of advanced filter media, sustainable materials, and construction approaches that enhance filtration efficiency, support and preserve service life, and reduce environmental impact while maintaining the performance standards customers expect.
Performance Testing
Systematic evaluation of products under conditions simulating real-world contamination levels, operating pressures, and temperature variations ensuring filters perform reliably when installed in actual vehicles and equipment.
Process Improvement
Ongoing refinement of manufacturing processes, quality control procedures, and production efficiency supporting consistent product quality while maintaining competitive cost structures that benefit customers through fair pricing.

Our Laboratory and Testing Capabilities
Consistent quality and reliable performance in filtration products are only possible with a robust testing infrastructure. With this understanding, our laboratory facilities are continuously upgraded in line with technological developments in the industry and current testing standards.
In our laboratory, raw material incoming inspections, process tests, and product performance tests are conducted in accordance with internationally recognized methods and current standards. This ensures that every stage of the production process is controlled and the performance of our products in the field is guaranteed.
Furthermore, in our measurement and calibration department, the calibration of all measurement devices used in production and testing processes is carried out in- house by trained and expert personnel. This approach sustainably supports measurement accuracy and test reliability.
Raw Material Input and Paper Performance Tests
The raw materials that form the basis of filter performance undergo detailed testing before being accepted into production. The main tests performed in this context are as follows:
Thickness Test
Grammage Test
Air Permeability Test
Burst Strength Test
Bubble Test (minimum and maximum pore measurement)
These tests verify the structural integrity, pore distribution, and filtration potential of the filter paper.
Air Filter Tests
The following tests are performed to evaluate the performance of air filters under demanding operating conditions:
Pressure Drop Test
Dust Holding Capacity Test
Initial Efficiency Test
Final Efficiency Test
Particle Efficiency Test
These tests reveal the filter’s effect on air flow and its dirt-holding capacity.
Fuel and Oil Filter Tests
In fuel and oil filters, leak tightness, mechanical strength, and long-term operating performance are of critical importance. The main tests performed in our laboratory are as follows:
Bypass Valve Opening Pressure Test
Valve Leakage Test
Valve Resistance Test
Pressure Drop – Flow Characteristic Test
Dirt Holding Capacity Test
Lifetime and Efficiency Test
High Pressure Differential Resistance Test
Particle Retention Test
Cleanliness Level Test for New Filters
Bypass Valve Lifetime Test
Durability and Safety Tests
Structural strength tests are also conducted to ensure filters can be used safely under real operating conditions:
Static Burst Test
Dynamic Fatigue Tests
Hydraulic Pressure Resistance Test
Fatigue Test
Bypass Valve Durability Test
Vibration Test
Valve Aging Test (150°C)
These tests aim to verify that filters maintain their performance under harsh conditions such as high temperature, pressure, and vibration.
An Approach That Ensures Quality Throughout the Process
