Ventilation Fan
A pneumatic mine ventilation fan clears blasting fumes and delivers fresh air to underground workings using compressed air rather than electricity. Vikay supplies the VK-PVF16 ventilation fan and VK-PAM air mover from India for metal mines, tunnels, gold mines and shaft sinking.
Re-entry time after a blast is a production constraint and a safety limit, and auxiliary ventilation is what shortens it. Running the fan on plant air rather than electricity removes cabling, isolation and flameproofing from the equation, which matters most in wet headings, shaft bottoms and freshly blasted ground where a power supply has not been established.
The VK-PVF16 pneumatic ventilation fan weighs around 25 kg, is fully balanced to run at 4000 rpm and is fitted with precision ball and roller bearings for long service in dusty conditions. The VK-PAM pneumatic air mover uses an induced-flow design to move a much larger volume of air than it consumes, and is typically used with ducting to ventilate a dead-end heading.
Applications include underground metal and gold mines, tunnelling, shaft sinking and confined-space ventilation.
FAQS
Why use a pneumatic ventilation fan instead of an electric one?
- Because it runs on the compressed air already reticulated underground, so it needs no cabling, isolation or flameproof enclosure. That makes it practical in wet, freshly blasted or temporary workings.
What is an air mover and how does it differ from a fan?
- An air mover uses a compressed-air jet to induce a much larger secondary airflow, with no rotating parts in the airstream. It suits ducted ventilation of dead-end headings and confined spaces.
What are the fan's basic specifications?
- The VK-PVF16 weighs about 25 kg, runs at 4000 rpm fully balanced, and uses precision ball and roller bearings for long life in dusty underground conditions.
