DUCTLESS FUME HOOD

What is a Ductless Fume Hood?

When you are handling volatile chemicals every single day, the equipment standing between your team and a serious health hazard cannot be an afterthought. That is exactly why laboratories, research institutes, pharmaceutical units, and educational facilities across India trust ACMAS as their preferred Ductless Fume Hood manufacturer. We understand that choosing lab safety equipment is not just a purchase decision, it is a promise you are making to every scientist, technician, and student who will stand in front of that hood, day after day, year after year.

So, what exactly is a Ductless Fume Hood? A Ductless Fume Hood is a self contained safety enclosure that filters toxic chemical fumes at the source and recirculates clean, breathable air straight back into your lab. Unlike traditional ducted systems, it needs no external exhaust connection, no complicated ceiling ductwork, and no expensive civil work. That means you get full chemical protection without tearing up your lab layout or waiting weeks for installation. If your facility values flexibility, faster setup, and lower running costs, a ductless system is very often the smarter choice over conventional ducted hoods.

Why ACMAS is a Trusted Ductless Fume Hood Manufacturer

As one of the most experienced Ductless Fume Hood Manufacturers in India, we build every unit around one core principle, the safety of the person standing in front of it. Our hoods are engineered with robust hood construction for long service life, a generously sized working area for real user comfort, and a heavy carbon filter bed that ensures uniform, dependable filtration across the entire working zone. The sliding sash glides smoothly, the microprocessor control system keeps a constant watch with audible and visual alarms the moment airflow conditions turn unsafe, and the front service panel opens easily whenever your maintenance team needs access. An optional VOC sensor continuously monitors chemical concentration inside the work zone, giving you an added layer of confidence.

Key Features and Custom Specifications

We also know that no two laboratories are alike, and that is precisely why, unlike many Ductless Fume Hood Suppliers who only sell off the shelf sizes, we are proud to say we can customize these equipments as per the technical specifications you provide us. Whether you need a wider working chamber, a specific socket type for your country, a different filter grade for a particular chemical class, or a size that fits an unusual corner of your facility, our engineering team will work directly with you to build a Ductless Fume Hood around your exact requirements, not the other way around.

Standards and Certifications

Every Ductless Fume Hood that leaves our facility is compliant with globally recognised standards including ASHRAE 110, EN 14175-3, AFNOR NF X 15-203, BS 7989, and BS 7258. This is not a marketing checklist, it reflects real, tested performance you can rely on when lives and research outcomes are on the line. The construction uses industrial grade fire resistant PCRC and pre coated corrosion resistant GI sheet, while the worktop is finished in acid proof glazed tiles or SS 304 grade stainless steel, so the unit stands up to years of chemical exposure without losing integrity.

How a Ductless Fume Hood Works, Operating Principle

Here is how the protection actually works. Air from the surrounding lab enters the hood through ergonomic openings, and the air face velocity creates a dynamic barrier between the operator and the chemicals being handled. The ventilation system then draws vapours and particles toward the filtration media, where they are captured before anything escapes back into the room. What comes out the other side is clean, purified air, continuously recirculated to keep the ambient laboratory environment safe. Our filters deliver 40 percent filtration efficiency for particles above 0.3 micron, and a built in programmable timer reminds your team every 60 hours to run a saturation check on the molecular filter, so protection never quietly degrades without your knowledge.

Noise, Lighting and Comfort at the Work Station

We also pay attention to the details that affect your team's day to day comfort. Noise levels stay below 60 decibels measured at roughly 15 centimetres from the sash, meaningfully quieter than typical industry benchmarks, and diffuser fluorescent lighting delivers up to 800 lux on the work table so close visual work never strains the eyes. A centrifugal, permanently lubricated fan with an external rotor motor keeps energy consumption and vibration low, while arm ports allow easy access to the work zone without ever exposing hands to fume pathways, and a recessed, spill retaining worktop contains accidental liquid spills before they become a bigger problem.

Available Sizes and Technical Details

Our standard range spans compact 4 by 2 by 2 feet units right up to spacious 6 by 3 by 3 feet chambers, with every dimension also available in fully custom sizes built to your specification. Choose from unidirectional airflow with a three step speed controller, stainless steel sinks with tap fittings, and epoxy or FRP lined coating depending on the chemicals you work with. Power requirements range between 500 and 750 watts depending on model, running on standard 220 to 230 volt, 50Hz single phase supply.

Ductless enclosure is a safety device used to protect laboratory workers when handling chemicals that pose an inhalation risk.

These enclosures are equipped with filtration technology that is specific to the type of chemicals handled. These filters capture toxic molecules and particles

evaporated in the hood and make it possible to:

Protect users in an effective manner
Reduce the carbon footprint by not releasing any toxic emissions into the atmosphere
Reduce operating costs due to their very low energy consumption
Eliminate all set-up costs related to the installation of a ducted airflow system.

Air intake through the openings
Air from the laboratory enters the hood through ergonomic openings. The air face velocity creates a dynamic barrier between the user and the chemicals being handled.
Filtration of particles and molecules
The device ventilation system draws the particles and any molecules that have evaporated in the hood toward the filtration system. The level of containment provided by the hood prevents any pollutants from being released into the laboratory.
Clean air into the laboratory
The filtration technology customized to the application traps the molecules that have evaporated within the enclosure. The discharged air is free from all pollutants.
Purification of the ambient air
The continuous recirculation of the filtered air helps to purify the ambient air of the laboratory.

Fume hoods are developed and designed to be used as semiconductor ventilated enclosures so as to protect the user from harmful and toxic fumes and vapors and to eliminate the possibility of accidental fire which may lead to emission of inflammable gases during the course of experiments. Hence, the materials of fume hoods are carefully chosen between industrial grades fire resistant thick PCRC, pre coated corrosion resistant GI sheet. The work table is made of heavy gauge construction material fortified with acid proof glazed tiles/stainless steel grade ss-304 grade. The work bench is provided with a small made of stainless steel ss-304 grade. All modular fume hoods are provided with sliding sash made of special grade shatter proof glass duly framed in wooden/ aluminum frame with sliding motion and counter weight balanced mechanism.
