Precision Filtration Manufacturing
Kenrax Industries is an established Indian manufacturer specialising in precision filtration products for industrial compressed air systems. Founded in New Delhi, India, we have over three decades of hands-on manufacturing experience serving compressor OEMs, authorised service partners, and industrial clients across the country and abroad.
Our in-house manufacturing facility is equipped with modern production machinery and staffed by a team of experienced engineers, quality professionals, and production specialists. We design and produce a comprehensive range of air filters, oil filters, air-oil separators, coolant filters, and hydraulic filters for rotary screw air compressors covering all major international and domestic brands.
We are not a trading house. Every product that carries our name is manufactured in our own facility, from raw material processing to final packaging. This gives us complete control over quality, lead times, and cost efficiency — advantages we pass directly to our partners.
Our mission is to serve as a trusted, long-term manufacturing partner for compressor brands seeking consistent quality, flexible production capabilities, and responsive service.
We offer end-to-end manufacturing flexibility, enabling OEMs to outsource their filtration product requirements with confidence. Our capabilities span the full product lifecycle — from initial design through to delivery and ongoing support.
Filters designed and manufactured to your exact specifications — from concept and prototyping to tooling, testing, and mass production.
Full customisation of branding, packaging, labelling, and part number mapping — your brand, your part numbers.
High-grade filtration media, adhesives, and raw materials sourced from trusted international suppliers.
From prototype batches of 50 units to high-volume runs of 50,000+, we scale to match your procurement cycle.
Direct manufacturing with no middlemen. Tiered pricing based on quality preferences, material choices, and order volumes.
Buffer stock for rapid fulfilment. Domestic shipping across India and international dispatch with your freight partners.
Material certificates, test reports, dimensional drawings, and compatibility data for quality management and regulatory filings.
A single point of contact for order placement, production updates, and post-delivery support.
Comprehensive filtration solutions for rotary screw air compressors, manufactured to meet or exceed OEM specifications.
Polyurethane-bodied air intake filters designed for durability and consistent airflow. Manufactured with precision PU encapsulation for a reliable seal and long service life.
Metal-cased air intake filters engineered for heavy-duty industrial applications. Rigid housing provides structural integrity under high-vibration and high-temperature conditions.
Coalescing separator elements with precision-pleated media for efficient oil removal. The pleated design maximises surface area, delivering low pressure drop and high separation efficiency.
Wrapper-type oil separator elements manufactured for reliable performance and consistent oil carryover control. Economical construction without compromising filtration quality.
Cartridge-based oil filtration elements that remove contaminants and protect compressor components from premature wear. High-grade filter media ensures efficient particle capture.
Convenient spin-on oil filter canisters for quick and easy replacement during routine maintenance. Built-in anti-drain valve and gasket for leak-free installation.
Replaceable oil filter elements designed for high-efficiency contaminant removal in compressor lubrication systems. Housing reuse reduces long-term maintenance costs.
Spin-on air-oil separator canisters that simplify maintenance while delivering consistent separation performance. Self-contained unit for fast turnaround during service.
Filtration solutions for compressor coolant systems, ensuring clean circulation and optimal thermal management. Removes particulates and sludge to protect heat exchangers.
Hydraulic fluid filtration products engineered to protect pumps, valves, and actuators from contamination. High collapse resistance and fine filtration ratings for critical circuits.
Our expansive manufacturing facility in New Delhi houses everything needed for end-to-end filter production — from raw material processing and media preparation through to assembly, testing, packaging, and dispatch. Every stage of the manufacturing process is controlled in-house, giving us full command over quality, consistency, and lead times.
High-precision pleating lines for cellulose, synthetic, and glass fibre media. Adjustable pleat height, depth, and spacing for diverse specifications.
Automated end-cap bonding and seam sealing for leak-proof, consistent seals. Supports metal and plastic end-cap configurations.
Polyurethane filling and potting systems with precise metering for uniform density, proper cure, and reliable circumferential sealing.
Precision thread winding and media wrapping for separator elements. Controlled tension and wrap angle for structural integrity.
In-house printing for branding, part numbers, barcodes, and multilingual labels. Complete white-label and private-label fulfilment.
Precision die-cutting for filter media, gaskets, and sealing components. Tight tolerances and clean edges for consistent fit.
High-performance adhesives and sealants imported from international manufacturers for thermal stability and long-term bond integrity.
Expansive facility with climate-controlled sections for sensitive media. Buffer stock maintained for rapid order fulfilment.
Custom branded packaging, protective wrapping, and palletisation. Packed to withstand domestic and international transit conditions.
On-site workshop for die maintenance, mould servicing, and equipment calibration to minimise production downtime.
Every product undergoes rigorous testing in our in-house quality laboratory. Our multi-stage inspection process — from incoming raw materials through in-process checks to final product validation — ensures consistent performance, dimensional accuracy, and reliability across all production batches.
Every separator and filter undergoes pressure testing under simulated operating conditions to verify structural integrity and performance before dispatch.
Particle capture rates and airflow characteristics are measured against industry benchmarks to ensure consistent filtration performance across batches.
Pressure drop across filter media is validated against specifications, ensuring optimal airflow with minimal resistance in compressor operation.
Products are tested to their structural limits to determine burst pressure margins and verify reliability under real-world pressure spikes.
Precision measurement of all critical dimensions — ID, OD, height, seal geometry, and fitment interfaces — ensures direct drop-in fit for the intended compressor model.
Incoming materials — filtration media, adhesives, metal components, and PU compounds — are inspected for quality and consistency before entering production.
Finished products undergo a final functional check covering fitment, seal integrity, and visual inspection before dispatch.
Statistical sampling across every production batch with sample retention for full traceability and quality assurance records.
