5.0 Maintenance and Cleaning
5.1 Filter Unit - Maintenance and Safety
The BVX-200 Fume Extraction System is designed with low maintenance in
mind. The housing is ESD safe plastic. Here are a few tips to keep your system
running in top shape:
To clean, use a light wipe with a gentle cleaner to prevent build up of
particulate and flux residue (be sure unit is turned off while cleaning).
Do not block both of the inlets or exhaust outlets; this will cause:
 the operating temperature of the system to rise
 a false filter-block alarm,
 potential damage to the unit,
 a drop in performance.
Do not defeat the filter interlock switch. Running the system without a
filter will allow particulates and flux residue to adhere to the blower, decreasing
the life of the system and increasing noise.
Do not lift system while operating.
Be sure to handle filters with care.
5.2 Filter Replacement Timing
Model BVX-201
As fumes are filtered inside the unit, any particulates captured will, over time,
start to clog the filter. The coarse particles are collected in the pre-filter while
fine particles will be collected in the HEPA filter. This clogging will result in a
reduction of the airflow, which may reduce the amount of fumes extracted from
the work area. Once the filters start to become blocked an audible alarm will
sound in the main unit. This is to signify that filter replacement is required.
Initially replace the pre-filter only. If this does not silence the alarm, then
replace the main filter too.
Dependant on application, pre-filters should be replaced approximately three to
five times as frequently as the main filter. We recommend that a stock of
replacement filters be kept for optimal extraction performance and minimum
down-time. Part Numbers are shown in section 8.2 of this User Guide.
