No compressed air
Manual filter shaker
A lever is connected directly to the filter. Moving the lever up and down compresses the filter, so the material comes off its surface and falls into the container.

Read the filter yourself
The gauge tells you when the filter needs attention.
On the Delfin machines a vacuum gauge on top of the machine shows the vacuum inside. It lets you follow how full the filter is, so you can plan maintenance before suction drops.
If the gauge shows an irregular value while the inlet is free
- 1Shake the filterUse the filter lever, with the machine switched off and the plug disconnected.
- 2Check the hoseMake sure nothing blocks the hose or the suction accessory you use.
- 3Clean or replace the filterIf the value does not improve, clean the filter or replace it.
Do not use the machine with a clogged filter.

Filter cleaning
Three ways to clean the filter.
How you clean the filter depends on the machine. The dust comes off the filter and falls into the container.
Compressed air
Automatic, pneumatic piston (PSC)
A pneumatic piston is connected directly to the filter. Its up and down movement compresses the filter, so the material comes off and falls into the container.
Compressed air, 6 bar
Automatic air jet (SP)
Each filter cartridge is cleaned at adjustable intervals by a high-pressure air jet. The jet shakes the cartridge and removes large amounts of material, so the filter is clean in a matter of seconds.
Source: Depureco dust collectors catalogue (EN), "Filter cleaning system". Delfin machines with a filter lever are shaken by hand with the machine switched off (Delfin manuals, section 7.3.3). Which system your machine has is shown on its product page.
Before you start
Service safely.
Six rules from the manual to follow every time you service the machine.
Switch off and unplug
Only service the machine when it is switched off. Disconnect the plug before you shake or change the filter.
Wait 10 minutes
After switching off, wait 10 minutes so the dust can settle before you empty the container.
Wear protection
The collected dust can be hazardous to health. Wear suitable personal protection, and a dust mask if the machine has an H filter.
Mark the machine
Put a sign on the machine: "Caution! Machine undergoing maintenance". Keep unauthorised people out of the area.
No open flames
Do not use naked flames or hot gases on or near the machine during maintenance.
Trained personnel
Maintenance must be carried out by qualified and authorised personnel.
For ATEX machines
The personnel need specific training in explosion prevention and protection. Use only original filters and spare parts: they are part of the explosion protection, and non-original parts void the ATEX certification and the legal guarantee.

FAQ
Service questions. Clear answers.
Short answers, each with the source it comes from. Didn't find your question?
Ask usHow often should I replace the filter in a dust collector?
The lifetime of a filter depends on how the machine is used. On the Delfin machines, the primary filter and the H filter must in any case be replaced every 12 months. Other brands and models can have different intervals, so always follow the manual for your machine.

How do filter reminders work?
Tell us which machine you have. We email you a service reminder with an offer, based on the manufacturer's recommended maintenance intervals. You decide whether to accept it. The work can be done by your own qualified staff, so you do not need to pay for a service visit. On ATEX machines, the staff must also be trained in explosion protection.

How do I know when the filter is clogged?
On the Delfin machines, a vacuum gauge at the top of the machine shows the vacuum inside, so you can follow how saturated the filter is. If the gauge shows an irregular value while the machine is running and the suction inlet is free, switch the machine off and disconnect the plug. Then shake the filter with the filter lever, check the hose and accessories for blockages, and clean or replace the filter if necessary. Do not use the machine with a clogged filter. On ATEX machines, act promptly when the vacuum gauge signals a problem. Ignoring it can lead to overheating or ignition of combustible dust.

When should I empty the dust container?
On the Delfin machines, check the fill level every 8 hours of operation and empty the container when the material reaches 3/4 of its capacity. Before emptying, switch the machine off, disconnect the plug and wait 10 minutes so the dust can settle. Wear suitable protective equipment, and a dust mask if the machine has an H filter.
Source: Delfin manuals, sections 8.3, 8.4.1 and 8.4.1.1
Can I service an ATEX dust collector myself?
Only if the person doing it is qualified and authorised. On ATEX machines, maintenance can itself become an ignition hazard, so the personnel also need specific training in explosion prevention and protection. Carry out maintenance only with the machine switched off, in a safe environment and at the intervals given in the manual. Maintenance work that is not described in the manual requires the manufacturer's prior approval.
Source: Delfin manual ZFR EV AP 560 Z22, sections 1.8 and 8.1
Who may change the filter?
It depends on the machine and on the dust. If the dust is hazardous to health, the filter may only be changed by trained staff wearing the protective equipment your internal rules require. On ATEX machines, the person who changes the filter must be trained in explosion protection, and the training can be internal. The filter must be fitted so that it still conducts static electricity away. Always follow the manufacturer's manual. You do not need an external service technician.

Why must ATEX dust collectors use original filters and spare parts?
On ATEX machines the original filters and spare parts are part of the explosion protection. Non-original parts void the ATEX certification and the legal guarantee, and the manufacturer accepts no liability for the machine if non-original spare parts are used. This applies to the Delfin ATEX machines. For other brands, follow the manual for your machine.
Source: Delfin manual ZFR EV AP 560 Z22, sections 8.1 and 8.5
Can I replace the motor myself?
Not on your own. The Delfin manuals say: to replace the motor, contact an authorised maintenance technician. If the motor is faulty or unusually noisy, contact technical support. Maintenance work that is not described in the manual may only be carried out with the manufacturer's prior approval, given in writing.
