Filter Type | Appropriate Use | ||
| HEPA | HEPA filters are |
|
2' | 3707900 | air filters having a particulate removable |
|
3' | 3707901 | efficiency of 99.99% for particles with a |
|
4' | 3707902 | diameter of 0.3 micron. |
|
Organic Vapor | Adsorbs organic compounds designated by |
| |
Activated Carbon | NIOSH guidelines as acceptable for use with |
| |
2' | 3937200 | chemical |
|
3' | 3937300 | Concentrations in the enclosure’s work area |
|
4' | 3937400 | must not exceed the IDLH for the chemical |
|
|
| and the exhaust from the enclosure must not |
|
|
| exceed the TWA. |
|
Formaldehyde | Formaldehyde requires the use of an |
| |
(Formalin) | impregnated carbon for the treatment of |
| |
2' | 3937201 | formaldehyde. Concentrations in the |
|
3' | 3937301 | enclosure’s work area must not exceed the |
|
4' | 3937401 | IDLH for the chemical and the exhaust from |
|
|
| the enclosure must not exceed the TWA. |
|
Ammonia and | Treats ammonia, low molecular weight |
| |
| Amines | amines and other bases designated by NIOSH |
|
2' | 3937202 | as acceptable for use with ammonia cartridge |
|
3' | 3937302 | type respirators. Requires the use of an |
|
4' | 3937402 | impregnated carbon. Concentrations in the |
|
|
| enclosure’s work area must not exceed the |
|
|
| IDLH for the chemical and the exhaust from |
|
|
| the enclosure must not exceed the TWA. |

Important: Carbon filters do not provide any particulate protection, but provide odor control.
Connecting the Electrical Supply Source to the Filtered Enclosure
115V Models
Simply connect the 115V power cord supplied to the IEC electrical supply plug on the back of the enclosure. If using at 50 Hz operations, blower performance maximum airflow will be reduced by 17%.
For the remote blower used for XPert Stations, follow the wiring diagram in Appendix C and wire the blower wires in the electrical junction box located behind the front panel. These wires are switched by the electrical relay via the blower switch.
