H201 FILTERED GUNS

INTRODUCTION

The H201 filtered gun is equipped with a heated filter in the service block to reduce nozzle clogging. The filter is readily accessible and easily removable for servicing and cleaning. An H201 gun is available for each Nordson non-circulating applicator.

Each gun uses either a standard thermos-tat or an RTD/solid state temperature control depending on the applicator used. There are three optional adhesive inlets and three optional filter drain ports located on each side and on the back of each gun in order to ease installation and servicing. Response time and cycle rates are similar to the standard H200 Series guns as standard extrusion modules are used.

The following list shows the part number of the gun specified for use with each Nordson applicator.

815 137 H201 filtered gun for 2000 Series P/N 815

applicators 139 H201 filtered gun for 2300/6000 Series applicators

SPECIFICATION SUMMARY

All specifications are the same as those for standard H200 Series guns (see Specification Summary under Section I of Manual 42-18), with the following exception:

Gun heating method RTD/solid state temperature control (for gun used with 2300/6000 Series applicators)

Thermostatically controlled cartridge heater (for guns used with all other applicators)

Filter Cleaning

Clean the adhesive filter once a week, unless operating experience indicates more or less frequent cleaning is required. A complete filter assembly is recommended as a spare for faster filter changes. The hot melt system must be at operating temperature before filter is removed for cleaning.

the following procedure to clean the adhesive filter.

Heat the system to application temperature.

Reduce pump air pressure to zero at the regulator (on applicators with piston pumps or air motors on gear pumps).

Momentarily trigger gun to relieve trapped hydraulic pressure.

Open the drain valve in the gun over an open container.

Increase pump air pressure until adhesive material flows steadiy from the drain. Allow material to flow until it is free of contaminants.

Reduce pump air pressure to zero at the regulator.

A 0 Failure to relieve system pressure can result in

+ r* serious burns when the filter assembly is removed for cleaning.

Unscrew filter assembly and remove from service block.

Using Figure 1 as a guide, remove screw (A) from filter bung (B) and disassemble filter.

Several methods for cleaning a hot melt adhesive filter screen (C) may be used, depending on the type of hot melt adhesive material used in the system, as noted below:

a, Place the filter in a container of Type R solvent and heat above the melting temperature of the adhesive. Scrub the screen with a fine bristle brush.

Some solvents may not be compatible with the hot

0 melt adhesive material. Sludge formation can further compound the problem, Test the solvent with a small sample of adhesive before using the solvent in the system.

0 Do not use a metal brush to clean a filter screen Damage may result to the screen preventing proper operation of the filter,

be Screens may be heated with a flameless electric heat gun and wiped clean with a dry cloth.

C, Use an ultrasonic cleaner filled with solvent to clean filter components.

d, Use a chemical cleaner to clean the filter components.

Inspect the screen for damage,

NOTE: Any dents or breaks in the mesh indicate damage beyond repair. Replace with a new screen

slide screen (C) over core (D), as shown in Figure 1.

Insert screw (A) through core and tighten screw into filter bung (B),

Inspect O-ring for damage.

NOTE: Any indication of cuts, nicks, hardening, or other physical damage constitutes O-ring failure, O-ring.

Replace

Screw filter assembly into service block, finger tight only.

Increase pump air pressure and purge filter as in step 5,

Close service block drain valve.

Tighten filter snugly. Do not overtighten.

0 Ensure gun is at operating temperature before the filter is tightened. Cold material on filter service block walls can cause filter screen to

and/or

collapse if filter is tightened in a cold system.
