Accessories
Mounting Screws for BANTAM Models
Mounting Brackets
Regulators and integrated filter/regulators can be mounted to a surface with a bracket that attaches to the regulator.
Brackets and mounting panel nuts can be ordered separately or in a kit which includes both bracket and mounting panel nut.
Modular Mounting Brackets
Two L-shaped metal brackets as shown at the right can be used for wall mounting of modular FRLs or Clean Air Packages. A single bracket can be used to mount individual filters or lubricators. Kits include two brackets and four screws for attaching
the brackets to the modules.
FRLs In-line Mounting Pipe Brackets
Two pipe brackets can be used for wall mounting of FRLs assemblies that use pipe nipples to join the components. The bracket kits listed below include two sets of brackets.
Mounting Bracket Assembly Kit for Pilot Operated Regulator
High-Relief Pilot Operated Regulator with 1/4- thru 11/4 inch ports can be mounted to a vertical surface using a bracket assembly kit.
MODULAR ASSEMBLY COMPONENTS – MID-SIZE, FULL-SIZE & BANTAM SERIES
MID-SIZE and FULL-SIZE Units
Connector Kite
Female Port Blocks
Male Port Blocks
The modular designs of the MID-SIZE and FULL-SIZE series offer maximum flexibility in customizing FRLs assemblies. As shown at the right, connector kits are required to interconnect units. Various port kits (shown below) can be used to connect
the assemblies to the inlet and outlet piping. Note that all FRLs components have threaded ports so that conventional pipe fittings may be used where desired.
BANTAM Units
End Plate & Connections
Pipe Ports
Tube Ports
BANTAM modular units use end plates secured with screws to hold the pipe or tubing ports (see below), and also to serve
as mounting brackets. Short screws are used to secure the end plates when a single BANTAM unit is used. If two or
more units are combined, long screws extend through an end plate and thread into the next unit. Screw kits required are as follows:
Single Unit: Two short screw kits.
Two-Unit Combination: One each short screw kit and long screw kit.
Three-Unit Combination: Two long screw kits.
MODULAR CONNECTION
Mounting Brackets & Clamp for Module Connections
Two brackets are normally used to mount an FRL to a vertical surface. The mounting bracket attaches to the module connecting clamp (see above) with a single screw. Each bracket then employs two bolts (1/4” or 6mm) to connect the assembly to the mounting surface. Specially designed clamps provide a quick and easy assembly or disassembly of MD3 TM modules. Two Allen-Head bolts quickly tighten or loosen the clamp using a 5/32 or 4mm hex key. The clamp contains a plate carrying two O-rings to provide positive sealing between modules.
Extra Port Blocks
An extra port block can be placed between modules to provide two auxiliary 1/4 NPTF ports. Its mounting position can be rotated to obtain the most convenient operating orientation. If only one auxiliary port is to be used, the unused port must be closed with a pipe plug. (The inlet and outlet are not threaded.
Male and Female End Ports
Either male or female end ports can be attached to threaded inlet and outlet lines. This allows all modules of an FRL assembly to be removed easily and quickly without having to unthread the end modules. The end ports are attached to the modules with clamps (see at left). End ports can be included in an assembled FRL or ordered separately.
