1. INTRODUCTION
This document is intended to provide information to assist with the installation, use, maintenance and replacement of
the Fike FlamQuench II.
Fike Corporation has designed and manufactures the FlamQuench II in two versions: an imperial size unit specified
according to NA standards, available in size 8” through 40”; and a metric version specified and built for the CE market,
available in size DN200 through DN1000.
2. GENERAL INFORMATION
2.1. Description
The Fike FlamQuench II is designed to allow for indoor explosion venting with flame arresting and particulate
retention. It consists of various layers of high temperature stainless steel that retain burned and unburned dust and
absorb heat produced during the explosion.
2.2. Service Qualifications
The information contained in this document is provided for reference purposes only. For further product information
or ordering replacement parts, please contact your local Fike Branch Office or Representative (details of which can be
found on the back page) or:
Fike Product Support by calling 816-229-3405 (fax: [phone]) or
Fike Europe Product Support at [phone] (fax: [phone])
2.3. External Effects
Tests conducted with FlamQuench devices indicated that
Maximum surface temperature at the flame arrestor mesh was 203°C.
a manikin located at 1 m from the device was not blown over and no visual burn damage to polypropylene
coverall (melting point 160- 165°C).
External noise measurements at 1 m and 5 m from the device resulted peak SPL 150 dB at 1 m and at 5 m
peak SPL 132 dB.
a dust cover slightly increased to noise levels but did not increase the Pred.
External pressures –at 1m and 5 m from the device resulted in peak values of 6.3 mbar and 0.8 mbar
respectively.
Refer to figure below for guidance on safety perimeter surrounding the flameless venting device.

PAGE / 4
Doc. P/N 8.8520.00.5
Rev. April, 2019
The FQ devices reduce the noise level compared to an open vent by ~10 dB(A). Fike recommends that the user
provide appropriate hearing protection for workers who may be in the vicinity (within 10 x D) of the vent device. Local
regulations may prevail.
2.4. FlamQuench II Safety
WARNING: Any damage to the Filter may cause the FlamQuench II to malfunction, which may result in a dust
explosion in the surrounding area.
2.5. FlamQuench Installation Procedure
WARNING: When installing do not damage filter. Any damage to filter may compromise the function of the
FlamQuench II.
Refer to Figure 1 (page 9) for assembly diagram.
1. All system components shall be installed and the electrical and control systems thoroughly checked by a
qualified technician before proceeding with installation.
2. Use provided lift ring(s) when installing FlamQuench II. The rings are located on the top and bottom
weldments. Do not attempt to lift FlamQuench II by any other method.
3. Carefully clean gasket, explosion vent, and bolting pad surface (frame or flangering).

Doc. P/N 8.8520.00.5
Rev. April, 2019
PAGE / 5
4. Place gasket onto bolting pad (AFM30/34 or similar is the recommended gasket material. Sealant may be
used, type may vary depending on process requirements). Be sure to line up holes.
5. Place the explosion vent onto gasket with ID tag lettering facing up. Align holes.
Note: Explosion vent may be placed onto the FlamQuench II first. However you must wait until the sealant has dried
before continuing the installation. Follow the instructions on sealant for drying time.
WARNING: TAKE EXTREME CAUTION NOT TO DAMAGE EXPLOSION VENT WHEN INSTALLING FlamQuench II.
DAMAGE TO THE EXPLOSION VENT WILL CAUSE IT TO MALFUNCTION.
6. Carefully place FlamQuench II on top of explosion vent making sure holes are lined up before placing all the
weight on the explosion vent.
7. Fasten the FlamQuench II to the bolting pad using either 18-8 or 304 stainless steel hardware. Torque to 35-
40 foot pounds (48-54 N-m).
8. Connect Burst Indicator. (See Installation Instructions on connecting BI)
Note: Cables attached to lifting rings can be used to help support the FlamQuench II. Do not attempt to support the
FlamQuench II using any other method other than the lift rings
2.6. FlamQuench Removal Procedure
Caution: Before removing FlamQuench II, carefully check the surface temperature. Make sure it is not too hot to
handle.
Do not disassemble the FlamQuench II when mounted to a vessel.
1. Shut down process if not already shut down.
2. Remove hardware holding FlamQuench II to vessel.
3. Use only the provided lift rings for lifting.
4. Follow instructions in Section 5 for refurbishment.
2.7. Identification of FlamQuench II
For the purpose of identifying the FlamQuench II and ordering replacement parts and refurbishment kits the
FlamQuench II has been permanently tagged. The FlamQuench II has separate ID tags for each component. See
Figures 4 & 5 for ID tag locations. The ID tags contain the following information: Size, Part Number and Lot Number.
The explosion vent will be marked separately.
3. INSTALLATION
Keep a minimum distance of 2 feet (0.7 meters) between the FlamQuench II and any equipment or walls to
allow for proper venting.
FlamQuench II may be installed anywhere between vertical and horizontal. See Figure 2. Fike Corporation
shall evaluate any deviation from this orientation.

PAGE / 6
Doc. P/N 8.8520.00.5
Rev. April, 2019
The FlamQuench II requires sufficient support based on the FlamQuench II weight and reaction force created
during activation. Refer to Table 2 or Table 3 and Figure 3 for FlamQuench II physical specifications.
4. SUPPORT CONSIDERATIONS
The FlamQuench II should be supported to prevent damage to the vessel it is protecting. If the vessel is sufficiently
sturdy, the flange connection may be used to support the FlamQuench II. Weight and angle must be considered when
evaluating vessel strength for mounting. If the vessel wall is not sufficient to support the FlamQuench II, additional
reinforcement should be provided.
Where lighter weight vessels are used, the FlamQuench II should be supported independently. This may be
accomplished by attaching cables to the lifting rings on the top and side of the FlamQuench II.Refer to Figure 2.
5. REFURBISHMENT INSTRUCTIONS
5.1. Filter Handling Warning
WARNING: To prevent possible injury (cuts & scrapes), wear leather gloves when handling the filters.
5.2. Filter Replacement
5.2.1. Remove Filter (fig. 4 & 5)
1. Follow removal procedures in Section 2.6.
2. Remove nuts, bolts and washers and discard.
3. Use supplied lift rings to remove Top Frame Weldment. Be sure to remove lower bands on larger
FlamQuench II.
4. Remove Top and Side Filters and dispose of properly.
5. Remove Fiber Frax rings and discard in a safe manner.
5.2.2. Installation of Filter(s) (fig. 6)
CAUTION: BEFORE INSTALLING NEW FILTER, THOUROUGLY INSPECT FRAME FOR STRESS FRACTURES. IF FRACTURES
ARE FOUND, REPLACE ENTIRE FRAME.
1. Place Fiber Frax ring into Bottom Weldment. Be careful not to tear ring.
2. Carefully install Side Filter into Bottom Weldment, ID tag down. If Filter is damaged in any way, it may
compromise the function of the filter. For easier installation turn assembly upside down to install filter. See
Figure 6A. Be sure to note location of ID tag (Refer to Figure 4 or 5).
3. Place Fiber Frax ring on top of Side Filter. See Figure 6B.
4. FlamQuench II sizes 8” – 20” (DN200 – DN500) skip to Step 9.
5. FlamQuench II sizes 24” – 40” (DN600 – DN1000) install Center Ring Support Weldment. (Refer to Figure 5)
6. Place Fiber Frax ring on top of Center Ring Support Weldment.

Doc. P/N 8.8520.00.5
Rev. April, 2019
PAGE / 7
7. Carefully install Side Filter into Center Ring Support Weldment
8. Place Fiber Frax ring on top of Side Filter.
9. Lay the Inner Top Filter on top of the Fiber Frax (ID tag up). Be sure to center this part on top of the Filter.
See Figure 6B. Be sure to note location of ID tag.
10. Lay the Outer Top Filter on top of the Inner Top Filter (ID tag up). Be sure to center. See Figure 6B . Be sure to
note location of ID tag.
11. Carefully lower Top Frame Weldment onto filter assembly. Align holes in top weldment with holes in bottom
weldment. In order to line-up holes the assembly needs to be compressed using 3 bar clamps. Place the bar
clamps equaly spaced around the diameter. Slowly tighten each bar clamp until the holes line-up. See Figure
6C .
12. Install new hardware provided. DO NOT USE OLD HARDWARE! Torque all hardware to 35 ft-lbs (48 N-m).
13. Refurbishment complete. Refer to Section 2.5 for installation.
