CAP-4 Ambient Air Pump0 pages

Description

TECHNICAL DATA SHEET

Note: For safe, efficient blasting, read
and follow the owner's manual and seek
training for everyone who will use this
equipment.

Purpose

The Apollo Ambient Air Pump conveys
breathing air from a clean-air environment outside the work area to low-pressure respirators worn by one to four operators inside the blast environment. The
CAP-4 pumps air to the respirators without introducing oil, carbon monoxide, or
other contaminants.

The Apollo Ambient Air Pump, model
CAP-4, is a cost-effective alternative to a
breathing air compressor. The CAP-4 provides oil-free breathing air for one to four
low-pressure type CE supplied-air respirators used for abrasive blast cleaning. It
can supply air to any NIOSH-approved
continuous flow hood or helmet style respirator approved to operate at 10 psi or
less. [ Note: Clemco offers single-operator model, CAP-1, Stock No. 22383. See
data sheet No. 21998.]

Requirements for Operation

The following items are required for
operation, but are not included with this
equipment:

• Compressed air supply between 30 and
70 cfm (depending upon the type and
number of respirators used) capable of
producing at a minimum of 85 psi with
respirators connected, not to exceed
100 psi
• One to four NIOSH-approved lowpressure, type CE supplied-air
respirators or up to six full face masks,
approved to operate at 10 psi or less,
and suitable for the application
• Appropriate approved respirator hose(s)
• Output from the ambient air pump must
meet the standard for Grade D
breathing air, as defined by the
Compressed Gas Association
Commodity Specification: G-7.1

Description of Operation

The Apollo Ambient Air Pump must be
placed outside of the blast environment in
an area free of airborne contaminants.
These potential contaminants include, but
are not limited to the following — fumes
from paints and solvents, exhausts from
vehicles and compressors, smoke from
burn barrels, and dust from abrasive blasting or other construction activities.
The ambient air pump moves air from a
clean location to supply low-pressure respirators. To increase its effective range,
the ambient air pump can be connected to
an optional remote inlet kit — which
allows the air inlet to be located up to 300
feet from the pump.

CAP-4C shown

Before blasting begins, and before putting on the respirator, the operator connects the respirator hose to the ambient
pump and to the fixed-orifice air inlet at
the respirator. The operator starts the
compressor, turns on the ambient air
pump, adjusts the pressure, and checks for
leaks, then puts on the respirator in a clean
environment.
After blasting, the operators keep the
respirators on and connected until they
reach an area free of airborne dust and
contamination.

The primary air connection uses a special quick-connect fitting that allows air to
flow, even when not connected to a respirator. This keeps hazardous dust or other
contaminants from entering the hose at the
connection point.

Advantages

• Supplies air for up to four blast
operators wearing type CE helmets or
up to six operators wearing full face
masks
• Eliminates the expense of separate
compressor for breathing air
• Uses compressed air for power; works
where no electric power is available
• Eliminates danger of carbon monoxide
poisoning caused when high temperatures break down compressor’s
lubricants
• Requires no temperature alarms or
additional air line filters
• Works with Clemco’s CO Monitor
Alarm (when specifications call for air
monitoring)
• Model CAP-4C includes integral twowheel cart and extendable handle
• Protective cage (both models) shields
critical components from damage
• Easy to operate and maintain
• Can serve as air source for other
respirators that operate at 9 cfm at
10 psi
