About This Product
Product Overview
Neelansh equipment & machines is a salient manufacturer, supplier & exporter of stainless steel/ Powder coated MS Laminar Air Flow. Laminar Air Flow is compatible in every working environments where it can be used in Pharmaceutical and Biotech.
A laminar air flow unit passes air through a HEPA filter and delivers it in a uniform, unidirectional stream over the work area, giving a Class 100 (ISO Class 5) zone for sterile and aseptic work. We build vertical, horizontal, ceiling-suspended and mobile models in SS 304 or powder-coated MS.
Every laminar air flow is manufactured in-house at our factory in Hadapsar, Pune. We supply, install and commission laminar air flow units across India, including Mumbai, Hyderabad, Chennai, Bangalore and Ahmedabad, and build each unit to your room layout, size and process requirements.
Guide
What is a laminar air flow and how does it work?
A laminar air flow (LAF) unit, also called a laminar air flow cabinet, laminar air flow chamber, laminar flow hood or clean bench, creates a small, particle-free work zone inside an ordinary room. Room air is drawn in through a pre-filter, pressurised by a blower and pushed through a HEPA filter that removes 99.97% or more of particles of 0.3 micron. The clean air then leaves the filter face as a uniform, one-directional stream that sweeps the work surface.
Because the air moves in parallel layers at a steady speed, usually around 0.45 m/s, particles are carried away instead of settling on the product. This keeps the work zone at Class 100 (ISO Class 5), the same air quality required for critical aseptic operations, even when the surrounding room is a lower class.
A laminar air flow protects the product, not the operator: air flows out of the work zone towards the person working at it. For work with infectious organisms use bio safety cabinets, and for weighing or sampling powders that should not reach the operator use dispensing booths.
Types
Laminar air flow types we manufacture

Vertical laminar air flow
The HEPA filter sits above the work surface and air flows down onto it. Less air is blown at the operator, and taller items and vessels fit easily. The usual choice for sterile pharma and microbiology work.

Horizontal laminar air flow
The HEPA filter forms the back wall and air flows across the work surface towards the operator. Suits flat bench work where items are placed in the cleanest first air.

Ceiling suspended laminar air flow
A HEPA module hung from the ceiling over a process, such as a filling or dispensing point, with clear PVC strip curtains around the zone below.
Applications
Where laminar air flow units are used
Sterile pharma operations
Aseptic preparation, sterility testing support and protecting open product during critical steps.
Microbiology and tissue culture
Media preparation, plating and plant tissue culture, where airborne contamination ruins work.
Hospitals and IVF
Clean preparation of non-hazardous materials in hospital pharmacies and labs.
Quality control labs
Clean sample handling and testing where results depend on a particle-free surface.
Electronics and optics
Assembly and inspection of parts that must stay free of dust.
Process zones
Ceiling suspended units create Class 100 zones over filling and transfer points inside larger rooms.
Buying guide
How to choose the right laminar air flow
Vertical or horizontal
Vertical for sterile pharma work, tall items or when you want less air on the operator; horizontal for flat bench work. Neither protects the operator from hazardous material. Either can be built on castor wheels as a mobile unit, so the clean zone can be moved between rooms or production lines.
Work zone size
Choose the working width and depth for what you handle and how many people work at it. We build to custom sizes.
Air velocity and class
Check the unit delivers a uniform velocity, typically 0.45 m/s ±20%, to hold Class 100 (ISO Class 5) at the work surface.
Construction
SS 304 for cleanrooms and frequent disinfection; powder-coated MS where budget matters and the room is less demanding.
Fittings
Magnehelic gauge to watch filter loading, UV germicidal lamp with hour meter, LED lighting, gas and air cocks, and sliding acrylic doors.
Testing and service
A PAO port makes HEPA integrity testing easy. Plan for velocity and particle checks at installation and at regular intervals.
How we work
From enquiry to installation
Every laminar air flow unit is built to order through the same six stages, so the unit fits your room and your process.
- 01
Planning: your room layout, process and transfer or work needs
- 02
Evaluation: size, airflow, filtration and material grade
- 03
Inspection: site measurements and wall or ceiling openings
- 04
Design: drawings shared for your approval before fabrication
- 05
Manufacturing: fabricated in-house at our Pune factory
- 06
Installation: delivered, installed and commissioned at your site

Questions
F.A.Q.
Do you provide customised size laminar air flow?
Yes, we are supplying customised size laminar air flow.
Do you provide mobile type laminar air flow?
Yes, we make mobile laminar air flow units mounted on castor wheels.
What is the difference between vertical and horizontal laminar air flow?
In a vertical unit the HEPA filter is above the work surface and air flows down onto it; in a horizontal unit the filter is at the back and air flows across the work surface towards the operator. Both give a Class 100 (ISO Class 5) work zone; the choice depends on the process and the space available.
Do you supply and install laminar air flow units outside Pune?
Yes. We manufacture in Pune and supply, install and commission laminar air flow units across India, including Mumbai, Hyderabad, Chennai, Bangalore and Ahmedabad. Share your requirement and we will send a quotation.
What air velocity does a laminar air flow need?
Around 0.45 m/s at the work zone, typically within ±20%, gives a stable one-directional flow and Class 100 (ISO Class 5) air. Our units are specified at 0.45 m/s to 0.65 m/s.
Can a laminar air flow be used for infectious or hazardous material?
No. A laminar air flow protects the product only, and its air flows towards the operator. Use a bio safety cabinet for infectious material and a dispensing booth for powders that must be kept away from the operator.
How often should the HEPA filter of a laminar air flow be checked?
Check the gauge reading routinely, and test HEPA integrity (through the PAO port), air velocity and particle count at installation, after any filter change and at the interval set by your quality system.
