Mifab MR-500-NPB 3 P.S.I Pressure Drop Activated Trap Seal Primer
6 drains served and a 1/2 ounce water output.
3 P.S.I PRESSURE DROP
Only a three p.s.i. line pressure drop is required to
activate the primer, compared to five or ten p.s.i. by others.
Lower water volume fixtures and faucets has resulted in
lower line pressure drops. A three p.s.i. performance point ensures reliable
water delivery to maintain the trap seal.
NO PRECHARGE
MIFAB’s trap seal primers can be disassembled in the field
for easy cleaning and repair, without risk of losing a pre-charge.
VIEW HOLES
Four view holes permit easy inspection of water delivery.
The holes are across from each other, enabling light at the opposite end to
illuminate the performance of the primer.
SEDIMENT FILTER
A replacement stainless steel sediment filter prevents line
debris from entering the primer. This can be replaced after wear and buildup of
debris to ensure maximum life and performance of the primer.
NO ADJUSTMENTS
The replaceable and repairable cartridge tubes inside of the
body are factory engineered to deliver enough water to service three, six or
ten floor drain traps without adjustment. This eliminates confusion during
field installation.
The M-500 Series of trap seal primers are tested and third
party listed to the A.S.S.E. 1018 Standard.
FUNCTION AND DESCRIPTION:
MIFAB’s M-500 Series of pressure activated trap seal primers can be connected to any cold
water line, and will be automatically activated when a valve or faucet, that is on the line, is
opened.
A pressure drop of three p.s.i. will activate all of the trap seal primers. MIFAB’s M-500
Series of trap seal primers can be disassembled in the field.
Their unique design permits filter
replacement without affecting the performance of the primer. The “O” ring seals are tested
for reliability at a temperature range of -40 degrees to 450 degrees F. The M-500 Series of
trap seal primers do not require adjustment.
The opening range for all of MIFAB’s M-500 Series
of trap seal primers is 20 to 80 p.s.i. All three models are listed with I.A.P.M.O. and C.S.A. and
are tested and certified to the A.S.S.E. Standard 1018 and are so marked. U.S. Patent #
