Atlas Copco Cobra PROi
Atlas Copco’s Cobra PROi gas
breaker is powered by a two-stroke,
90 cc engine with an electronic fuel
injection system that minimizes fuel
consumption and ensures smooth
operation. The breaker’s engine control
unit activates during the first
revolutions after a user pulls the starter
cord, so operators can start the breaker
in almost any climate or at any altitude.
Despite its compact size and low
weight of only 53 lb (24 kg), the Cobra
PROi breaker delivers as much as
44 ft-lb (60 J) of breaking force due to the unique
arrangement of its gearbox percussion system.

Qdos and APEX Pumps for Aquajet EcoClear
Qdos and APEX pumps from Watson-Marlow Fluid
Technology Group (WMFTG) are key components in the
latest generation of the EcoClear water treatment system from
Aquajet Systems AB. EcoClear allows the discharge of
hydrodemolition water back into the environment without the
use of filters. Recent improvements to EcoClear include new
software functions that optimize dosing to control the pH and
turbidity of the treated water. Dosing is facilitated by three
Qdos chemical metering pumps that provide high-accuracy
metering at pressures up to 100 psi (690 kPa). A single APEX
hose pump is used to discharge settled sludge from the
EcoClear storage hopper. The pump’s direct-coupled drive
delivers reliable performance in a compact footprint.
