Achieve rapid heating with this
furnace's ionic fl ame
The e-Ion Zapper furnace (photo) provides
non-contact, continuous heating
with accurate temperature control in
a compact package. The furnace features
a non-combustion flame that
is comprised of ions in a controlled
atmosphere. Capable of delivering
the high heating rates required for
melting, brazing and heat-treating,
this furnace requires a lower residence
time than traditional heating
methods, such as induction, allowing
for rapid processing in air and a
number of other gases. - Micropyretics

This tiny plastic air nozzle
resists harsh chemicals
The PEEK Atto Super Air Nozzle
(photo) delivers a small, precise blowoff
with an efficient, high-volume,
high-velocity airflow. The overall
length of the air nozzle measures only
1/2 in. (12.7 mm) with a diameter of
only 0.16 in. (4 mm), permitting installation
in tight spaces. Its plastic
construction does not mar production
items and is resistant to damage from
harsh chemicals. Safe operation is
assured, since the airflow of the Atto
Super Air Nozzle cannot be blocked,
which meets the OSHA standard for
dead-end pressure. - Exair Corp.,

This respirator routes exhaled air
downward to prevent fogging
The Series 6500 Rugged Comfort halffacepiece
reusable respirator (photo)
can withstand long hours and extreme
conditions, while maintaining comfort
of wear. The over-molded design also
offers users simplified cleaning and
maintenance, while protecting them
from harmful dusts, gases, vapors and
sprays. The respirator's soft, but firm
silicone faceseal holds up in high heat
and is equipped with polyester straps.
The low-profile design allows for compatibility
with other personal protective
equipment and includes a valve

A safety light curtain with a
very small footprint
The GL-S safety light curtain (photo)
provides simplified installation in applications
where space constraints
are a major concern. Available in both
front- and side-view models, these two
designs allow the GL-S to be seamlessly
installed into areas with tight
dimension restrictions. The smallfootprint
design features highly visible
three-color indicator lights that
show the curtain's operational status.
Illuminating red, green or orange, the
indicators can be controlled externally
to indicate work steps, reducing the
need for additional equipment. The
GL-S also offers a built-in muting
function, external device monitoring
and an interlock function. Ease of in24

stallation is key, as the GL-S comes
with built-in brackets and selectable
wiring options. - Keyence Corp. of

This self-lubricating material is
approved for potable water use
This company's Hilube self-lubricating
bearing material has recently been
NSF/ANSI approved for potable water
applications. Used for bushings in
pumps, dam gates, valves and aerators,
this material allows for lower friction
than rubber materials even when running
dry at startup. Hilube materials
require no greasing and have no water
swell, allowing them to achieve closerunning
clearances. Many stock shapes
are available and extra-large bushings
(greater than one meter) can be specially
made. - VescoPlastics Sales, Pty
