• 2-Stage Adsorbent Filling
• Distribution of Flow by special design of the inner components
Visual Indicator
• S
tar-pleated air filter element (2 µm) reduces/prevents dirt and dust
ingress into tank
The visual indicator shows by percentage
the increase in vacuum pressure drop across
the element. The percentage remains visible
even when the system is turned off. When the
element is changed a manual reset button
must be pressed.
• Integrated anti-splash tool to protect the absorbent from oil
contamination
• Replacement Cartridges
• C
olor Indication: When maximum adsorption is reached, the silica
gel turns from purple to orange
• Optional visual indicator
