Before you choose

Is it right for your dust?

The manual sets clear limits. If your dust, process or area is on the “Not permitted” list, this machine is not the right choice.

Permitted

Suction and filtration in ATEX zone 22 classified areas
Combustible dust with a minimum ignition energy (MIE) above 3 mJ
Material that is no warmer than the ambient temperature
Filters chosen to suit the dust, based on its chemical and physical properties and safety data sheet

Not permitted

Use in zones 0, 1 and 2 (gas) or zones 20 and 21 (dust)
Dust with a minimum ignition energy (MIE) of 3 mJ or less
Self-igniting or exothermic dust, incandescent particles, oxidising dust and explosive substances
Flammable liquids, hybrid mixtures, liquids, or dust wetted with solvents
Connection to machinery that can generate ignition sources

Self-igniting or exothermic dust?For this type of dust, Delfin recommends the wet-type Inert version.

See the Inert version

Not sure about your dust?The MIE of many dusts is listed in BIA-Report 12/97. Or ask us before you choose.

How it works

Two filters. Four steps.

The air passes through two stages of filtration before it leaves the machine. Heavier material drops straight into the container.

Simplified illustration, not to scale.

01Dusty air inThe extracted air enters the machine through the Ø200 mm suction inlet.
02Heavy material drops outThe heavier material falls straight into the 100 l container.
03Primary filterThe dusty air passes through the star filter, which captures the dust.
04Clean air outThe air passes the secondary filter and leaves through the clean air outlet.

Stage 1 · Primary filter

> 95%

Star filter in antistatic polyester ANT M, 50,000 cm².

Stage 2 · Secondary filter

ATEX marking

What the marking means.

Every part of the marking on the type plate tells you something. Here is what it means for this machine.

1II

Equipment group II: intended for use in surface industries.

23

Category 3: normal level of protection, suitable for use with an external zone 22.

3D

For explosive atmospheres caused by combustible dust.

4Ex h

Explosion protection for non-electrical equipment. For this machine, Delfin states protection by constructional safety of the filter unit.

5IIIC

Dust subgroup for conductive dust, for example metal powders.

6T80°C (int)

Maximum surface temperature inside the machine.

7T135°C (ext)

Maximum surface temperature on the outside of the machine.

8X

Special conditions for safe use apply. See below.

9Dc

Equipment protection level (EPL) for dust.

The X: special conditions

To avoid electrostatic charge, the manual sets three conditions.

Clean the outside only with a damp cloth or antistatic products.
Clean the machine regularly, so that dust layers never exceed 5 mm.
Connect the earthing clamp to a metal surface in contact with an earthing point.

Hoses

Hose diameter and length affect airflow, conveying velocity and pressure loss. Select the hose based on the material, application and system requirements.

AIRDUC PUR 351 EC (MD)Recommended for the Ø200 inlet. Conductive PUR hose, internal Ø202.3 mm. Vacuum rating 0.05 bar (DIN 26057), 0.19 bar when axially fixed. CP PE 457 ECConductive clamp-profile hose. The standard choice on swivelling extraction arms.

The machine reaches up to 370 mmH₂O, about 0.036 bar, which is within the rating of AIRDUC PUR 351 EC (MD). Check the inlet fit: the fit on the inlet spigot is not documented. Hose and accessories must be electrically continuous, so that static electricity from suction is led to earth.
