ATEX extraction unit for gases and vapours, 1,000 m³/h - ULT ACD 1200.0-MD.46.00.1012

Flammable gases and vapours need more than air flow: filters, housing and fan have to stay free of ignition sources. The ULT ACD 1200 MD.46 A46 Ex captures 1,000 m³/h at 1,800 Pa, is tied into an equipotential bonding system throughout and carries an explosion proof fan to ATEX Ex II 2G h IIB T3 Gb.

Benefits

• Explosion proof fan to ATEX Ex II 2G h IIB T3 Gb, temperature class T3 with a maximum surface temperature of 200 °C
• Headroom up to 1,700 m³/h volume flow and 2,600 Pa vacuum for longer duct runs
• Two A23 adsorption filter cassettes with 23 kg of activated carbon each, 46 kg in total
• Upstream M5 filter mat keeps dust particles away from the activated carbon
• Electrically conductive filter cassettes with equipotential bonding connection, exchange filter system for low contamination removal
• Protection class IP55 and 62 dB(A) at 100 percent air performance thanks to integrated sound insulation
• Controls in a remote starter box, mobile unit on castors

Limits of use

The unit is designed for dry flammable and non-flammable gases and vapours at concentrations below 20 percent of the lower explosion limit with a low dust content. Gases of temperature classes T1, T2 and T3 with an ignition temperature above 200 °C can be extracted. Installing or operating the unit inside a classified explosive zone is not permitted.

Applications

Bonding, pre-treatment, painting, printing, cleaning, laminating and casting. The flow reserve also supports branched ducting with several capture points, and the unit roof carries a Ø 160 mm mount for an extraction arm.

Compatibility and scope of delivery

Filter set A46 Ex: M5 filter mat (ULT 4-00248), A23 adsorption filter cassette top (ULT 4-00397) and A23 adsorption filter cassette bottom (ULT 4-00396). These are storage filters, replaced completely once saturated and reordered individually under the ULT numbers listed. An operating hour meter for Ex units is available as an option (ULT 9-00100). The filtered clean gas may be returned to the workspace. With carcinogenic, mutagenic or reprotoxic substances recirculation is not permitted, in that case the exhaust spigot is fitted on the outlet side and the clean gas is ducted into a central exhaust system.
