INTRODUCTION
The BF840 Room Filter is a heavy duty auxiliary air filtration unit designed
to neutralize residual formalin fumes in the busiest of laboratories.
At peak workloads, many large facilities find themselves exceeding OSHA
recommended exposure rates for formalin and are forced to temporarily
shut down or operate at limited capacity. Equipped with two replaceable 40
lb (18 kg) potassium permanganate and carbon mixed filters, the BF840
has the horsepower to rein in formalin overexposure and maintain
a safe laboratory environment.
The BF840 is constructed all of stainless steel and is equipped with a 9’ line
cord with hospital grade plug. Casters enable easy positioning of the BF840
through out any lab, allowing easy filtration of problem areas.

Operation:
The unit has a three way switch, Hi, Off and Low.
Upon turning the unit on, the pressure gauge will read 0 as depicted in the
picture below.
Through use, a slow steady deflection to the right will occur; this indicates
the pre-filter filter is working. As the gauge approaches 2.0 in of water
column the pre-filter filter needs to be changed.

This is a differential pressure gauge. From this point of calibration, a 100%
blockage of the filters will yield a reading of .5 in of W.C.

How to change filters:
BF023 Merv13 Pre-filter:
Open the cover by pulling upward on the handle. The Pre-filter can be lifted out of the
holder and replaced by new media. The media should be firmly inserted into the holder
frame so that it seats to the bottom of the frame. The arrow on the filter should point
towards the inside of the module. See photo below
BF014 Combination Potassium and Charcoal Filter
With the cover open simply pick up the black plastic filter casing and dispose of in
accordance with your hospital guidelines. The new filter is placed in the unit with the
opening of the filter towards the top of the unit as shown in the above photo. See
Cleaning and maintenance section on how to check the filter for replacement.

GENERAL PRECAUTIONS
Introduction of liquid into the unit will create a shock hazard for operators and
personnel in the area. In addition will void any associated warranty of the motor
and filter unit.
Operation, use and maintenance of this unit not in accordance with this manual
might damage unit for which Mopec will not be responsible.
Replaceable filter elements, both Pre-filter BF023, BF021 Potassium
Permanganate and BF014 Combination Media filter are to be replaced by the
customer at their own cost.
Unit should not be operated with panels removed or doors open.

CLEANING AND MAINTENANCE
EVALUATING FILTERS FOR REPLACEMENT
The filters in your BF840 unit contain activated charcoal and alumina pellets
impregnated with potassium permanganate, KMnO4, which is a fast oxidizer.
Formaldehyde passing through the filter is converted to carbon dioxide and water.
The filter’s life depends entirely on the amount of formaldehyde fumes passing
through the filter.
The pellets are bright purple when new and become dark brown when spent. Once the
inner part of the pellet is brown it is totally spent and must be replaced. This chemistry is
very effective and essentially removes all formaldehyde as long as there is active KMnO4
available. The efficiency drops off as the filter media approaches its maximum capacity.
The last 15-20% capacity will exhibit some pass through of formaldehyde.
PROCEDURE - EVALUATING FILTERS FOR REPLACEMENT
On one side of the filter there are four tabs which can be opened to allow pellets to be
removed. (see photo)
Eye protection is recommended based on the
above “Health Hazard Data”.
The usefulness of the filter is approximately 80% diminished
when the purple color first disappears from the core.
To determine when the KMnO4has been exhausted, remove a
pellet and slice it in half. Place the sliced pellet(s) on a paper
towel and add a few drops of water. The water running off the
pellet(s) should be initially purple and then turn a deep iodine
color. If no purple coloration is present, the KMnO4is totally
spent.
When the purple color first disappears from the core of the pellet as described above,
the rate at which formaldehyde is removed from the air stream is slowed considerably.

Health Hazard Data
-
Alumina Permanganate Filter Media
Effects of Exposure – The filter media is non-toxic upon oral, skin, and inhalation exposure and is non-irritant of the
skin. Breathing of dust may cause sneezing. Skin may feel dry after contact. The filter media is an eye irritant.
Emergency Treatment – Flush eye with large quantities of water and seek medical attention.

CLEANING AND MAINTENANCE
PROCEDURE – SUMMARY OF EVALUATING FILTERS FOR REPLACEMENT
From a practical standpoint, it may be desirable to perform the tests on the preceding
page more frequently during initial usage of the filters to determine when the purple first
begins to disappear from the core of the sliced pellet. Based on these early
observations, the user can establish a Replacement Testing Cycle with occasional re-
checks for verification.
All stainless steel surfaces can be cleaned with soap and water, which will remove
debris.
The stainless steel surfaces can be disinfected with a non caustic disinfectant. We
suggest using BE045 PathCloud or BE047 Bench Wipe for cleaning purposes.
We recommend you NOT USE a bleach solution to clean your unit. Bleach will
eventually erode stainless steel if not thoroughly rinsed. The use of chlorine bleach will
VOID THE STAINLESS STEEL WARRANTY
