Pre-Pump Protection Vacuum Traps & Inlet Accessories

Features:

• Neutralizes acidic vapors
• Element changes color when spent
• Contains large alkaline element for neutralization
• For high vapor loads, place a cold trap between acid neutralization trap and pump

1420H-20 Features:

• Used for High Flow Pre-Pump Protection
• Made for DN 25 KF (NW25) connection
• For pump FAD 101 to 500 L/min (6 to 30 m3/h)

1420H-21 Features:

• Used for Low Flow Pre-Pump Protection
• Made for DN 16 KF (NW16) connection
• For pump FAD less than 100 L/min (6 m3/h)

1420H-14 Features:

• Removable center making trapping surface easy to clean
• Has a large, 3 quart (2.8 liters) center well for the dry ice/isopropyl alcohol slurry or liquid nitrogen
