1 Introduction
Fann’s Series 300 LPLT Filter Press is used for measuring filtration and wall-
building properties of drilling fluids and cement slurries. The filtration rate is the
fluid loss measured in milliliters at ambient temperature and 100 psi (690 kPa)
through a special filter paper for 30 minutes. Wall-building characteristics are
demonstrated by the thickness and consistency of the filter cake (the residue)
deposited on the filter paper after 30 minutes. The filter cake is measured to the
closest 1/32 in. or the nearest millimeter.
The low pressure filter press assemblies described in this manual consist of the
following items:
filter cell mounted in a frame
pressure assembly and regulator
filter paper, the filtering medium
25 ml graduated cylinder, the filtrate receiver
The filter press cell body, top cap, and base cap are constructed of 303 stainless
steel.
The filtering medium is filter paper that has been especially hardened for filtrate
testing.
Pressure sources deliver the required pressure, 100 ± 5 psi (690 ± 35 kPa) and can
be any of the following:
compressed nitrogen or air in cylinders,
carbon dioxide gas cartridges,
high pressure air or water systems,
dead-weight hydraulic pressure assembly
Compressed oxygen should not be used as a pressure source.
Fire and explosion hazards exist when using oxygen.

1.1 Document Conventions
The following icons are used in this manual.
NOTE. Notes emphasize additional information that may be
useful to the reader.
CAUTION. Describes a situation or practice that requires operator
awareness or action in order to avoid undesirable consequences.
MANDATORY ACTION. Gives directions that, if not observed,
could result in loss of data or in damage to equipment.
WARNING! Describes an unsafe condition or practice that if not
corrected, could result in personal injury or threat to health.
ELECTRICITY WARNING! Alerts the operator that there is risk of
electric shock.
HOT SURFACE! Alerts the operator that there is a hot surface and
that there is risk of getting burned if the surface is touched.

2 Safety
Safe operation of filter presses requires that the laboratory technician or drilling
fluids engineer be familiar with the proper operation and potential hazards
associated with this equipment. For instance, if the filter cell or pressurization
equipment has a leak, then sample or pressurizing fluid could be released and cause
serious injury.
Several precautions that should be observed are described in this section.
2.1 Safe Pressurization
2.1.1 Gases
Always use nitrogen, carbon dioxide (CO2), or compressed air. Never connect
the LPLT Filter Press to oxygen, natural gas, or any other non-recommended
gas.
Compressed oxygen should not be used as a pressure source.
Fire and explosion hazards exist when using oxygen.
Nitrogen must be supplied from an approved nitrogen gas cylinder. Nitrogen
cylinders must be secured and meet all safety standards.
Carbon dioxide is normally supplied in small cartridges, which contain about
900 psi (6205 kPa) pressure. They are primarily used for field operations.
Do NOT allow carbon dioxide cartridges to be heated or exposed
to fire. They can explode if overheated.
If compressed air is used, its maximum pressure should not exceed 150 psi
(1035 kPa) at the regulator inlet.

2.1.2 Pressure Regulators
Maintain pressure regulators in good condition. Never use oil on pressure
regulators.
Pressurization systems that leak should be repaired or replaced.
Gauges, fittings and hoses should be kept in good condition and leaks should be
corrected.
Periodically test the safety relief valves on the pressurization manifolds to
verify they will relieve if excessive pressure should occur. Never plug or bypass
these safety valves.
When pressurizing the cell, always make sure that the regulator is closed (i.e.,
Tee screw backed all the way out, counterclockwise). Then open the supply
pressure, and adjust the regulator.
Do NOT attempt to pressurize higher than 100 psi (694 kPa).
Follow the pressurizing procedures in Section 4.
When depressurizing, first shut off the supply pressure. Then bleed the system
of pressure, and back out the regulator Tee screw (turn counterclockwise),
following the procedures in Section 4.
