Filtration system for safety/acid cabinets

Standalone filtration unit for fire proof and chemical storage cabinets

Combine fire safety and protection from inhalation of noxious chemicals for High - Low - Underbench Fire proof and Chemical Storage Cabinets.

Chemtrap H402 Smart - for high and low fire proof and chemical storage cabinets - and Chemptrap V201 Smart - for underbech fireproof and chemical storage cabinets - filter the air from the internal chamber of a storage cabinet, capture noxious fumes right at the source and return clean air back into the laboratory while contributing to a purer and safer working environment. Designed as a standalone system with no need for ducting, it is equipped with an adjustable flexible hose for an easy connection to the exhaust of your existing cabinet.

Equipped with the highest efficiency filtration system, Chemtrap H402 Smart and Chemptrap V201 Smart now integrate an innovative and straightforward mode of communication called Smart Technology. This technology uses simple light and sound alerts to show that the unit is operating safely so you can focus your attention on what is most important: your work.


FiltrationSimple to useSafetyCompatibility

Erlab’s unique filtration system connected to the fire proof or chemical storage cabinet can be adapted to filter gases, chemicals fumes and particles keeping the user and the lab protected by safely and efficiently cleaning the air of the room from hazardous vapors or odors.

New optional sensors for the monitoring of filter performance can be added for the detection of solvents or acids or formaldehyde.

SMART technology embedded into each Chemtrap H402 and Chemtrap V201 filtration unit informs users about their protection using light and sound.Light and sound pulses give real time information about:

•• Filter alarm
••• Fan alarm

User protection

The ChemTrap filtration system eliminates noxious vapors generated by chemicals stored in a safety or acid cabinet.

Simple and easy

No ducting is needed. A simple and fast connection with a universal pipe fitting.

Laboratory air purification

ChemTrap filters the air from a safety/acid cabinet's internal chamber, captures and retains toxic fumes, and returns clean air back to the laboratory.

    Simple, intuitive safety communication by light and sound pulsations show the status of the unit.
  2. Mute alarm button
  3. Ethernet port for remote safety monitoring.
  4. Automatic filter performance alarm.
  5. Hydraulic pistons for fast filter housing access.
  6. Erlab’s unique flex filtration technology allows combination of carbon and HEPA filters for filtration of gases and particles.
  7. 4 possibilities to connect to the storage cabinet: left, right, back (connections with a flexible hose), or direct connection from the bottom
