Micro-Irrigation
Drip
Drip In® PC
Pressure Compensating Dripline
A technologically superior
and cost effective
way to irrigate
• Difficult topographical conditions
• Low and varying water pressures
• Installations requiring longer lateral runss
Features & Benefits:
Highly clog resistant
Due to wide, deep turbulent passageways
and raised inlets.
Extremely accurate flow rate
Due to high quality control standards.
Reduced labor and installation cost
No hole punching, lost emitters or handling
damage. Emitters are factory spaced.
Can’t separate
Because there are no clip-ons or connections.
Lower friction loss
Due to jointless design, allows longer runs and
fewer mainlines.
Versatility
Flow rates available in three hose sizes:
(0.550" (16mm), 0.620" (18mm) and 0.710"
(20mm)

Design Advantages:
High Resistance to Plugging
Water enters the emitter through a raised filtration
system. Debris is deflected upward and away from the
inlet because of the unique construction of the emitter.
This feature significantly reduces the amount of debris
entering the emitter when the system is operating. The
positioning of the raised inlet also prevents sediment from
collecting near the inlet while the system is not operating,
and being ingested into the emitter at start-up. The
emitters filter ensures that only particles smaller than the
emitters cross sectional dimensions will enter.
Three flushing cycles to ensure continued
reliability and performance.
1.Pre-regulating Flush:
The automatic flushing feature is activated at low
pressures during system startup. The diaphragm is
relaxed allowing particles to be freely flushed out.
2.Irrigation Flush:
During the irrigation cycle the diaphragm is depressed
across the compensating chamber. If the emitter begins
to clog, there is a reduction of flow, and pressure
on both sides of the diaphragm begins to equalize.
The diaphragm returns to its relaxed position and
particles are flushed out. The dripper returns to normal
performance.
3.Shut-down Flush:
As pressure is reduced, the diaphragm returns to its
relaxed position allowing accumulated particles to be
flushed out.
Wide Compensating Range
At low pressures, 10 - 15 psi, the emitter behaves like a
turbulent-flow emitter. From 15 - 60 psi, the emitter is
fully pressure compensating.
Flat discharge curve over a wide range of pressures (10-60 PSI)
Chemical Resistance
Drip In PC is manufactured from the highest quality
materials. The emitter body is made from injection
molded polyethylene resins. The diaphragm is made
from silicon. This combination will withstand acids down
to pH2 as well as most commonly used ag chemicals,
fertilizers and chlorine.
Uniformity
Drip In PC’s state of the art manufacturing process and
high quality control standards assures dependable,
uniform and precise emitter discharge. Drip In emitters
have Cv values less than .05, one of the highest rankings
of all manufacturers.

The growers most economical choice
for vineyards, orchards, and row crops.
Advantages:
• Highly clog-resistant due to wide, deep
turbulent passageways and raised inlets.
• Extremely accurate flow rate due to
high quality control standards.
• Reduced labor and installation cost. No
hole punching, lost emitters or handling
damage.
• Can’t separate because there are no
clip-ons or connections.
• Lower friction loss due to jointless
design, allows longer runs and fewer
mainlines.
• For above and below ground
applications.
• Emitters are factory spaced, thus
requiring no field installation
(hole punching, clip-ons, etc.).
The In-line Emitter is enclosed and
inseparably welded to the inside wall
of the tubing as it is extruded in the
manufacturing process. This emitter
has enjoyed over 20 years of reliable
performance in a variety of applications.
Pressure Compensating Dripline is a
one piece, jointless emitter enclosed tube.
It is rugged, lightweight and very flexible.
It can be laid out and re-rolled easily
with no damage to the in-line emitters.
Only the highest quality resins are used.

economical choice for permanent or row
crops. PC dripline now comes with the
Toro Ag Irrigation Blue Stripe of quality.
High Speed Installation and Removal
In addition to high speed layout and
recovery, tractor-mount spindle reels
provide convenient storage between
seasons, plus easy shipment and handling.
Built-in emitters make
Drip In® the ideal dripline for quick,
damage-free re-rolling through dense
crops like tomatoes or cotton.

Drip In dripline comes factory-installed
with clip rings.
• Dramatically reduces labor and
installation time in the field.
• Unique engineering plastics provide
unparalleled strength on the wire.
• Superior control of water placement by
directing water droplet to the plant.
• Low profile for mechanical harvesting.
• Works with 14 gauge wire.

Drip In® Rootguard
ROOTGUARD protection technology
combines Treflan® with the drip emitter
to inhibit root growth. This is a patented
technology where the herbicide is
released at a uniform rate over a long
period of time. It maintains a sufficient
concentration in the soil immediately
surrounding the drip emitter, to prevent
root growth into the emitter.
