Types of banner printing machine fans
A professional banner printing machine usually consists of Two main types of fans They use:
1. Dryer fans (usually 12×12 size)
✅ Installation location: In front of the device and above the banner exit point
✅ Quantity: Usually one or two rows (depending on the width of the device and model)
✅ Application:
- Fast drying of ink on the banner
- Preventing color from spreading or smudging the print
- Preparing the banner to roll up without sticking
✅ Fan type: Most industrial cooling fans are 12 x 12 cm in size. Some models come with a heating element and produce warm air.
2. Spiral fan (vacuum fan)
✅ Installation location: Under the machine, in the lower part of the tray or printing table
✅ Application:
- Air suction under the banner
- Attaching the banner roll to the flat surface of the machine
- Prevents wrinkles, waves, and lifting of the banner when the head moves.
- Improve printing accuracy and increase output quality
✅ Fan type: High suction helical fan (crystal fan or centrifugal fan). These fans are designed to pull air out from the floor, creating a partial vacuum on the print surface.
Why is the performance of the fan of a banner printing machine so important?
❌ If the dryer fans are not working properly:
- The banner sticks to the head of the device.
- The color is spreading.
- The edges of the print are smudged.
❌ If the vacuum fan is weak:
- The banner wrinkles when printed.
- The edges of the print are shifting.
- The resolution of the design decreases and the probability of the head colliding with the media increases.
✅ Result?
Increased printing failures and reduced output quality = time and financial loss for the printing house operator!
