port
•Provides a constant ‘differential’ of 3-5
PSI (21-35 kPa) to maintain a ‘positive’
pressure at the orifice
•HS23 bubble rate ‘pre-set’ at factory
Manifold
Purge
valve
•Uses ‘dry nitrogen’ cylinder
Flow
tube
•Eliminates risk of silicon oil entering
‘riverline’
•‘Quick Connect’ fitting available for field
check of bubble rate
Riverline
port
•Available in ‘dual-line’ or ‘dual orifice’
versions
Bubble Unit
Typical Installation
Air Compressors – General
•Alternative to gas cylinders (Safety Issues)
•Effective air drying system essential - moisture ingress
- aquatic growth
•Some Limitations – ‘riverline’ length < 200 metres
- maximum head of 30 metres
•Low powered types available (12V: 38aH with solar)
•Can be used with either standard orifice (BU07) or large volume type
GCO1P
HS45 AND HS55 COMPRESSORS
•Bubbler type system
•Two stage air dryer
•12V Compressor
•HS55 comes with HS23 bubbler
