A modern, highly functional laboratory cabinet designed for the safe storage of chemical reagents and volatile substances.

## What is a ventilated chemical cabinet? {#what-is-a-ventilated-chemical-cabinet}

A **ventilated chemical cabinet** is a laboratory cabinet in which a fan continuously draws air from the interior and passes it through an activated carbon filter. Reagent vapours do not build up inside the cabinet or escape into the room when the door is opened. On our model, the filter-fan unit sits on the top panel, so the cabinet needs no connection to the building's ventilation system and can be installed where there is no extraction duct. Our guide to choosing a [ventilated chemical cabinet for reagents](https://www.renggli.pl/en/blog/ventilated-reagent-cabinet-laboratory) explains how to match the cabinet to the type of reagent.

## Ventilated or fire-resistant cabinet? {#ventilated-or-fire-resistant-cabinet}

A ventilated chemical cabinet is intended for reagents that give off vapours but are not flammable: concentrated acids, alkalis and other volatile substances. It has no fire resistance, so solvents and other flammable liquids must not be stored in it. These belong in [90-minute fire-resistant safety storage cabinets](https://www.renggli.pl/en/offer/safety-storge-cabinets/specialized-safety-cabinets-90m) or 30-minute models to EN 14470-1. Where substances are corrosive but do not give off much vapour, an [acid and alkali storage cabinet](https://www.renggli.pl/en/offer/safety-storge-cabinets/chemical-storage-cabinets) with a duct for connection to an extraction system is sufficient. The situations that call for a ventilated cabinet are covered in our article on [when a ventilated chemical cabinet is needed](https://www.renggli.pl/en/blog/ventilated-chemical-cabinet-when-is-it-needed).

## Carbon filter: inspection and replacement {#carbon-filter-inspection-and-replacement}

The activated carbon filter captures vapours until the carbon becomes saturated with the substances stored in the cabinet. How often it needs replacing depends on the type and quantity of reagents, the room temperature and how often the door is opened. The cartridge is therefore replaced according to the filter manufacturer's recommendations and inspection results, not on a single schedule for all cabinets. When replacing it, record the date and a list of the substances stored: at the next inspection it is then easier to judge whether the filter is saturating faster than usual.

## Construction and tray shelves {#construction-and-tray-shelves}

The cabinet carcass is made of chipboard permanently bonded to polypropylene sheet. The chipboard provides rigidity, while the polypropylene on the inside withstands acids, alkalis and moisture. The interior is fitted with fully extending shelves, each with a polypropylene tray. The raised tray edges contain the liquid if a container starts to leak, and full-depth extension gives access to bottles at the back without reaching deep into the cabinet. Reagents with different hazards are best kept on separate shelves, so that a leak cannot bring an acid into contact with an alkali.

Thanks to its advanced hybrid construction and integrated filter ventilation unit, the cabinet guarantees the highest level of work safety in the laboratory, eliminating the risk of harmful vapors escaping into the surroundings.

## Key features and construction

- **Hybrid body construction** The main body of the cabinet is made of high-quality chipboard permanently bonded to polypropylene (PP) board. This combination provides excellent structural rigidity while making the interior completely resistant to aggressive chemicals, acids, bases and moisture.
- **Pull-out tray shelf system** The cabinet interior is fitted with convenient, fully extendable drawers/shelves. This design gives easy access to stored containers across the full depth of the cabinet, and raised edges effectively prevent substances from spilling if reagent containers leak. As standard, each pull-out shelf has a tray made of polypropylene board.
- **Integrated, self-contained filtration system** A filter ventilation unit is mounted on the top panel of the cabinet. It is designed to filter and neutralize toxic and flammable vapors from cabinets (e.g. concentrated acids, bases and non-flammable substances). It does not need to be connected to an existing ventilation system: thanks to the activated carbon filter, unwanted vapors are cleaned and released into the atmosphere without posing a threat to the environment or human life.

## Frequently asked questions about ventilated chemical cabinets

**When should I choose a ventilated chemical cabinet?**

A ventilated chemical cabinet is the right choice for reagents that give off vapours but are not flammable, where the room has no extraction duct or running one to it would be difficult. The activated carbon filter cleans the air from inside the cabinet, so vapours do not reach the room. Flammable liquids require a fire-resistant safety storage cabinet to EN 14470-1.

**How often should the carbon filter be replaced?**

There is no single interval for all cabinets. The service life of the filter depends on the type and quantity of reagents stored, the temperature and how often the door is opened. The cartridge is replaced according to the filter manufacturer's recommendations and the results of saturation checks. It is worth recording the replacement date and a list of the substances stored, so that at the next check you can judge whether the filter is being used up faster than usual.

**Is a ventilated chemical cabinet suitable for flammable liquids?**

No. A ventilated chemical cabinet has no fire resistance, so it does not protect its contents during a fire. Solvents, alcohols and other flammable liquids are stored in fire-resistant safety storage cabinets tested to EN 14470-1, of either the 30-minute or the 90-minute type. A ventilated chemical cabinet is intended for acids, alkalis and other volatile non-flammable substances.
