Installation: Drainvac SEPA.INOX01 SEPA.INOX02 Dry Separator Owner Manual

Overview

The SEPA.INOX01 SEPA.INOX02 Dry Separator range is designed for industrial central vacuum systems that collect large debris or fine dust. Both models use a stainless-steel main separator, a cartridge filter, and an automatic filter-cleaning system to help maintain airflow and protect the external motor.

The SEPA.INOX01 is intended for larger debris and discharges collected material through a pneumatic door into a waste container. The SEPA.INOX02 is designed for fine dust and releases material through a flap into a mobile container. These separators are suited to installations that require continuous dust collection, accessible maintenance, and a separate safety separator between the main separator and motor.

Detailed Description

The main separator receives material drawn through the central vacuum piping. The separator retains the collected material while finer airborne particles are directed toward the cartridge filter and safety separator. The safety separator works between the main separator and external motor to help keep volatile dust away from the motor assembly.

Important components include the wall brackets, main separator, cartridge filter, compressed-air tank, safety valve, manometer, pneumatic door or dust flap, mobile container where applicable, and external motor. The SEPA.INOX01 uses a pneumatic door that closes when suction begins. The SEPA.INOX02 uses a flap that closes as vacuum is established.

The cartridge filter is cleaned automatically whenever the system starts and stops. During this cycle, compressed air passes from the inside of the cartridge toward the outside, dislodging accumulated dust across the filter surface.

Safety

• Use the separator and vacuum system only for their intended industrial application.
• Do not collect burning or smoking items, including cigarettes, matches, hot ash, or hot debris.
• Never vacuum flammable liquids, fuels, solvents, explosive materials, or combustible substances.
• Avoid hard or sharp objects that could damage or obstruct hoses and plastic piping.
• Keep every opening free of dust, lint, hair, and other restrictions. Reduced airflow can cause the motor to overheat.
• Keep hair, clothing, fingers, and other body parts away from suction openings.
• Never handle the plug, electrical components, or power units with wet hands.
• Disconnect electrical power before performing motor disassembly or internal inspection.
• Keep the external motor screen clear so the motor can draw in and exhaust air correctly.

Preparation

Plan the installation before lifting any equipment. Separators must remain accessible for dust removal, filter service, and inspection. Provide at least 36 inches (1 m) of open space around the external motor. This clearance is required for effective ventilation and future maintenance.

The recommended installation tools include an 8 mm (5/16-inch) socket, Phillips and flat-blade screwdrivers, cutting pliers, a measuring tape, a drill with a 12.5 mm (0.5-inch) bit, a box saw, a mitre saw, a 2-inch (50 mm) PVC pipe cutter, and a 2.25-inch (57 mm) punch.

Measure the collection canister before installing the SEPA.INOX01 so the wall-bracket position leaves adequate space below the separator. For the SEPA.INOX02, the main wall bracket is installed 95 inches (241 cm) above the floor, after which the mobile canister base is positioned below the separator.

Setup and Installation

Install the SEPA.INOX01

1. Measure the height of the waste canister that will sit below the separator.
2. Add that measurement to the 38-inch (96.5 cm) distance from the bottom of the closed door to the wall bracket.
3. Mark the resulting bracket position on a suitable wall structure.
4. Secure the wall bracket using appropriate wall fasteners. Fasteners are not supplied with the unit.
5. Lift the separator onto the wall bracket.
6. Check that the separator is upright.
7. Secure both side brackets with two screws on each side.

Install the SEPA.INOX02

1. Secure the wall bracket 95 inches (241 cm) above the floor.
2. Lift the separator and hang it on the wall bracket.
3. Confirm that the separator is vertical.
4. Fasten both side brackets with two screws on each side.
5. Place the canister on its mobile base.
6. Move the base directly below the separator.

Install the Safety Separator and Air Tank

1. Mount the safety separator bracket at the same height as the main separator.
2. Lift the safety separator onto its wall bracket.
3. Check that it is straight.
4. Secure its two side brackets with two screws on each side.
5. Connect the compressed-air tank to the air compressor.

Install the External Motor

1. Choose an indoor or outdoor motor location with unobstructed ventilation.
2. Position the motor on a stable floor.
3. Maintain 36 inches (1 m) of clearance on every side.
4. Use all six mounting holes to anchor the motor to the floor.

The stainless-steel motor housing allows indoor or outdoor installation. In a typical system layout, the pinch-valve assembly, emergency valve, and control panel are installed indoors, while the external motor may be installed outdoors.

System Operation

Starting

The external motor starts gradually when the hose is connected to an inlet or when the system is switched on manually. The cartridge filter cleaning cycle begins immediately. On the SEPA.INOX01, suction closes the pneumatic coarse-debris door and holds it shut. On the SEPA.INOX02, vacuum pressure closes the fine-dust flap.

Stopping

If the system has no separate switch, removing the hose from the inlet stops the vacuum. The filter-cleaning cycle is triggered again, and the separator door or flap releases so collected material can fall into the container below.

Automatic Filter Cleaning

The unclogging system uses compressed air to clean the cartridge from the inside outward. This automatic action occurs at system start-up and shutdown, helping remove dust before it significantly restricts airflow.

Piping Installation

Route the piping so the separator, safety separator, valves, control equipment, and motor remain accessible. Use smooth connections wherever possible to reduce turbulence and material buildup.

For wall plates, use joints with sufficient wall thickness and no internal obstruction. Avoid fittings with internal stops or sharp projections that can catch debris, reduce the passage area, or contribute to blockages. Cut PVC piping cleanly, remove burrs, and ensure each connection is fully aligned before securing it.

Cleaning and Maintenance

Cartridge Filter

Clean the cartridge filter at intervals determined by the type and quantity of material collected. Dusty or fine materials may require more frequent servicing. Keeping a second filter available allows one cartridge to dry while the other remains in service.

1. Remove the cartridge according to the system configuration.
2. Blow compressed air from the inside of the cartridge toward the outside.
3. Rinse the filter with clean water.
4. Allow the cartridge to dry completely before reinstalling it.

External Motor

• Inspect the motor’s wire mesh regularly and keep it free of dust. Use compressed air when cleaning is required.
• Clean the cooling fan with compressed air every 1,000 operating hours.
• At 5,000 operating hours, inspect the motor air inlet and outlet. If dust is present, access and clean the turbine.
• At 15,000 operating hours, arrange replacement of the motor’s two ball bearings by a qualified service provider.

Use the hour meter to organize preventive maintenance and reduce unexpected shutdowns.

Access the Turbine

1. Switch off the motor’s circuit breaker.
2. Remove the ten Phillips screws securing the black panels.
3. Remove the two black panels. The front panel can be positioned over the air inlet and outlet to avoid disconnecting electrical wiring.
4. Remove the six Allen screws securing the casing to the base.
5. Unscrew the lifting ring.
6. With assistance, lift the box from the motor assembly.
7. Use locking pliers to remove the base of the lifting ring.
8. Remove the cover panel by taking out its five 19 mm (3/4-inch) bolts.
9. Remove the seven 8 mm Allen screws and four T20 Torx screws holding the motor cover.
10. Carefully lift the cover with a flat-blade screwdriver.

Protect the cover edges during disassembly. Damaged or contaminated edges can compromise the motor’s watertight integrity.

Clean the Turbine

Do not use water or cleaning solutions inside the motor. Remove dust and debris from each turbine blade with dry cleaning methods. Clean the motor housing and surrounding components as needed. Before reassembly, remove all fine dust from the mating edges of the cover and motor.

Troubleshooting

• Reduced suction: Check the cartridge filter, safety separator, piping, and motor screen for dust buildup or obstruction. Clean the filter and confirm that all airflow paths are open.
• Motor overheating: Verify the 36-inch clearance around the motor and make sure the wire mesh, cooling fan, inlet, and exhaust are unobstructed.
• Separator does not empty: Confirm that the collection container is correctly positioned and that the pneumatic air supply is connected. Inspect the door or flap for debris that could prevent release.
• Frequent filter clogging: Increase filter-cleaning frequency according to the collected material and consider rotating a second cartridge filter.
• Dust near the motor: Inspect the cartridge filter and safety separator. Make sure the filter is correctly installed, fully dry, and free from damage or excessive blockage.

Waste Electrical and Electronic Equipment

The system falls under waste electrical and electronic equipment requirements. Do not dispose of the unit with unsorted household or commercial waste. Arrange end-of-life handling through an authorized recycling organization or the applicable municipal waste service so the equipment can be processed correctly.
