Vacteck designs and manufacturers a wide range of anti static pneumatic vacuums. These systems are intrinsically safe in explosive and hazardous environments as they are powered by air and there is no ignition source, no moving parts and no heating component. Vacteck's anti static vacuums come in both wet and dry models.

Read what a trained consultant says about Vacteck's range of anti static vacuums;

The above apparatus is intended to remove combustible and flammable liquids
(and other matter) by means of a vacuum applied to the reservoir (2), created by
the air motor and pump assembly (3), and collected by the metal wand (6).

POTENTIAL ELECTRICAL IGNITION SOURCES – THIS APPARATUS
The apparatus above contains no electrical sources of ignition and is bonded
to the system earth in order to prevent any build up of static electricity, therefore
preventing ignition by electrostatic sparking.
POTENTIAL MECHANICAL IGNITION SOURCES – THIS APPARATUS
From the manufacturer’s statement, there are no moving parts in either the motor
or pump assembly that can produce heat from friction. The particulars of this
device are subject to an application for a Patent and may not be discussed
further.
Therefore no heat generating mechanical components exist within the apparatus,
based on an affirmation from the manufacturer and designer of the air motor and
pump assembly.

This apparatus, by its nature and design, is inherently and unconditionally safe in
a constantly hazardous explosive or combustible atmosphere as there are no
ignition sources or mechanisms for ignition incorporated within it, under normal
operation.
Certification under any national or international explosion protection scheme,
including ATEX Approval or IECEx Certification or to any explosion protection
standards is therefore unnecessary as this apparatus is outside of the scope of
these schemes and those standards

Based on the above analysis and the supplied data by both Vacteck and the
manufacturers of the air motor and pump, it is the opinion of E.P.E.E. Consulting
Services that the apparatus as described above of this Letter of Opinion is
inherently and unconditionally safe in explosive, flammable or combustible
atmospheres in that it will not ignite explosive mixtures of flammable gases,
vapours or mists, combustible mists or combustible dusts, during normal
operation.
