Alpha Linear has been our preferred partner and supplier of contamination control and cleanroom equipments like Sampling Booths, Dispensing Booths, and Laminar Air Flow Clean Benches for over 15 years. They have continued to work with us for validation services and ensured uninterrupted equipment performance over the years with a great team of support staff. We would highly recommend Alpha Linear to anyone looking to purchase their products and services.
UPL Limited
As a research company, we use standard instruments in our work with most care to get great results. Our entire operations are depending on the quality of equipment we use. We have carefully evaluated many Laminar Flow units, and finally decided to go with Alpha Linear. We successfully installed Laminar Air Flow Clean Benches from Alpha Linear across several facilities of UPL Limited. We are delighted with the quality and performance of the LAFs. The constant support of sales and technology team was great. We highly recommend Alpha Linear to anyone evaluating or planning to consider their cleanroom equipment, laboratory furniture or validation services.
Rakon India
Private Limited
We have procured products from Alpha Linear, including Vertical Laminar Flow, Model: 2436-V a total of 4 Units. All are installed and working fine.
Since this was the first business transaction, we were a bit concerned about the supplier.
But, after receipt and installation, and careful monitoring of the equipment performance over time and their support staff responsible for delivery, repair and maintenance, we can safely say we took a very good decision in choosing their equipment.

India’s Leading Cleanroom Equipment Manufacturer & Solutions Provider
Alpha Linear is India’s foremost cleanroom equipment manufacturer and contamination control solutions provider with over 30 years of uninterrupted expertise. Headquartered at Peenya Industrial Estate, Bangalore, we design, manufacture, supply, install, and validate a comprehensive range of cleanroom equipment — including biosafety cabinets, laminar flow cabinets, air showers, pass boxes, fume hoods, PCR workstations, RLAF dispensing booths, and HEPA air filters. We also deliver end-to-end cleanroom solutions — from concept design to full ISO 14644-1 and GMP validation — serving over 2,000 customers across pharmaceuticals, biotechnology, hospitals, electronics, and research institutions throughout India.
Cleanroom Equipment — Our Complete Range
Alpha Linear manufactures India’s most comprehensive portfolio of CE-certified, ISO-compliant contamination control equipment. Each product is application-engineered and backed by 30+ years of field experience.
Biosafety Cabinets
Our biosafety cabinets provide triple protection for the operator, product, and environment. Available in Class II Type A2, Class II Type B2, and Class III configurations. All feature H-14 grade HEPA filtration (99.999% efficiency), DC ECM motors for 40% energy saving over AC motors, microcontroller-managed constant airflow, and stainless steel 304/316 inner work surfaces. CE certified to EN 61010-1:2010 & EN 61326-1:2013.
Laminar Flow Cabinets
Alpha Linear’s laminar flow cabinets maintain ISO Class 5 (Class 100) particle-free environments for cell culture, sterility testing, pharmaceutical compounding, and electronics assembly. Available in vertical LAF (downflow, ideal for tissue culture and media preparation) and horizontal LAF (cross-flow, preferred for optics and sterility testing) configurations.
HEPA Air Filters
Our HEPA air filters are the filtration backbone of every cleanroom and laboratory ventilation system. We supply the full spectrum — mini pleat HEPA filters for low-pressure-drop applications, deep pleat HEPA filters for extended-life pharmaceutical terminal filtration, pre-filters/panel filters for HEPA protection, coarse filters for HVAC intake stages, and fine filters for intermediate filtration efficiency classes.
Air Showers
Air showers are HEPA-filtered personnel decontamination chambers installed at cleanroom entry points. High-velocity air jets (20–25 m/s) remove surface particles and fibres from gowning before entry, protecting the cleanroom classification from human-borne contamination. Available in single-person, double-person, and tunnel configurations with mechanical safety interlocks.
Pass Boxes — Static & Dynamic
Pass boxes enable material transfer between zones of different cleanliness classifications without requiring personnel to physically cross the barrier. Static pass boxes use UV sterilisation and mechanical interlocks. Dynamic pass boxes add HEPA-filtered positive-pressure air circulation for ISO Class 5 transfer environments required in pharmaceutical aseptic manufacturing.
RLAF Dispensing Booths
Reverse laminar airflow (RLAF) dispensing booths protect operators and the surrounding environment during pharmaceutical raw material weighing, dispensing, and sampling. The inward airflow design creates an effective containment barrier, meeting EU GMP Annex 1 and Schedule M requirements for pharmaceutical dispensing suites.
Fume Hoods
Laboratory fume hoods are local exhaust ventilation enclosures for safe handling of volatile solvents, concentrated acids, toxic gases, and odoriferous compounds. Note: fume hoods provide chemical protection only. For biological hazard work, a biosafety cabinet is required.
PCR Workstations
PCR workstations provide UV-sterilisable, HEPA-filtered enclosures that prevent amplicon contamination during PCR sample preparation and molecular biology work — a critical control in diagnostic and research laboratories processing high-sensitivity nucleic acid assays.
Operation Theatre Laminar Flow
Operation theatre laminar flow modules deliver a continuous H-14 HEPA-filtered downflow curtain over the surgical site, providing an ISO Class 5 environment that reduces surgical site infection (SSI) rates in orthopaedic, cardiac, and organ transplant procedures. Designed to HTM 03-01 and NABH guidelines.
Laboratory Furniture & Support Equipment
Alpha Linear also supplies laboratory furniture, garment storage cabinets, and cross over benches — the complete ecosystem of supporting equipment required for a functional, compliant cleanroom environment.
