1 INTRODUCTION
1.1 About This Manual
This document is organized with the most important information toward the front of the manual. All
users should read and understand the sections on setup, operation, and maintenance. Toward the
back are sections that provide in-depth information on subjects such as maintenance and parts.
These sections should be consulted as needed.
This manual is periodically revised for maximum accuracy and to incorporate new features or
updates. User feedback is welcome. Electronic versions of this manual are available upon request.
1.2 Technical Service
Should support still be required after consulting the printed documentation, contact one of the expert

Please have the instrument serial number available when contacting the manufacturer. On most
models manufactured by Met One Instruments, it will be located on a silver product label on the unit,
and also printed on the calibration certificate. The serial number will begin with a letter and be
followed by a unique four or five digit number such as X12345.

1.3 Sharp Cut Cyclone
Figure 1-1 BX-807
The BX-807 Sharp Cut Cyclone (SCC) is a PM2.5 size selective inlet for use in ambient particulate
monitoring. It is a non-US-EPA designated device. This lack of designation means that any data
collected using the BX-807 cannot be considered as FRM 2.5 equivalent. For applications requiring
this designation, the Met One Instruments, Inc. BX-808 or BX-809 size selective inlets must be
used.
The BX-807 may be used with any of the following Met One Instruments, Inc. products:
•BAM 1020
•BAM 1022
•E-BAM
•E-BAM Plus
•E-FRM
•E-SEQ-FRM

2 INSTALLATION
Use the following information to properly deploy the BX-807. Installation of the SCC should ideally
be performed by personnel familiar with environmental monitoring equipment. There are no special
precautions or handling concerns except for the normal level of care required for handling scientific
equipment. Refer to the instructions and diagrams on the following pages.
2.1 Unpacking
Unpack the cyclonic separator and inspect it carefully. Any damage incurred to the equipment
during shipping is the responsibility of the carrier. If any damage to the shipment is noticed before
unpacking, a claim must be filed with the commercial carrier immediately. Follow any special
unpacking instructions provided by the carrier as all items are carefully removed from the containers
and each component inspected. It is recommended to document and photograph all damaged
packages and items before, during, and after unpacking them. Contact Met One Instruments, Inc.
(see section 1.2 of this manual) to arrange for any replacement items needed.
Please keep all of the special shipping items (box, foam packing material, etc.) used to ship the
SCC. They should be re-used if the BX-807 is to be transported or shipped (changing site locations,
returning to the factory, etc.). Contact Met One Instruments, Inc. (see section 1.2 of this manual) for
replacement packing materials if necessary.
2.2 Instrument Assembly and Deployment
The BX-807 is designed for easy deployment. It is installed on top of the sample inlet tube as a
second stage after the BX-802 PM10 inlet. Follow the installation instructions of the instrument with
which the SCC is being used. For example, if deploying as part of a BAM 1020 installation, the
setup instructions in the BAM 1020 operation manual should be followed.
Figure 2-1 Typical BX-807 Installation
Once the BX-807 is installed, verify all O-rings are functional and a proper seal has been achieved
by performing a leak check on the system. The instructions for performing a leak check will also be
found in the operation manual of the instrument with which the SCC has been deployed.

3 OPERATION AND MAINTENANCE
The BX-807 is designed to operate with an airflow rate of 16.67 LPM. After passing through the
PM10 separator, the sample air flows down into the top of the SCC, through the cyclonic separator,
into the grit pot, and then exits the bottom of the BX-807 after passing through the top cap and
transfer tube (see Figure 3-2 for component labels). The airflow path is shown in Figure 3-1.
Proper configuration and operation of the instrument with which the SCC is being used will be
necessary to maintain the required airflow rate. See the operation manual of the associated
instrument for details.

3.2 Disassembling the BX-807
An exploded view of the BX-807 is shown in
Figure 3-2. It demonstrates how the BX-807 comes apart for cleaning. Recommended cleaning
materials are clean mineral free water and lint free lab wipes. In cases where stubborn deposits are
observed, ultrasonic cleaning is recommended.

To disassemble:

BX-807-9800 REV C Page 9
1. Remove the BX-807 from the sampling line.
2. Pull off the transfer tube. If it is too tight to remove by hand, pry it off with a rigid plastic lever.
Plastic should be used to avoid damaging the protective finish.
3. Remove the top cap and the grit pot by unscrewing them.
4. Wet a lint free wipe with water and remove all visible deposits. These are most likely to be
found at the bottom of the cone inside the grit pot.
5. Inspect the O-rings for shape and integrity. If any deformation or cracking is noted, all O-rings
should be replaced. When installing new O-rings, lightly lubricate them with O-ring grease. In
particular, the top cap and main body O-rings should be well lubricated for ease of installing
the transfer tube.
6. Reinstall the SCC and then verify all O-rings are functioning properly. This should be done
by performing a system leak check as described in the operation manual of the instrument
being used with the BX-807.
