Applications and Benefits of Smoke Eliminators
|
Applications Falls Filtration Technologies vacuum pump exhaust smoke eliminators are designed to eliminate the finely divided oil smoke found in gases discharged from rotary types as well as droplets from reciprocating-type vacuum pumps. These lightweight units can be mounted directly on the pump, or on a discharge pipe common to several pumps. Yet, they are versatile enough to allow remote mounting. The units may be installed indoors or outdoors. And the in-line models allow clean exhaust from the eliminator to be piped to a remote location or back into process. Enjoy these benefits Lube oil collected from the exhaust can be drained to an independent oil reservoir or returned to the pump if system permits ... Air from thee pump is clean and free of oil smoke. Clean exhaust helps guard against pollution and adds to in-plant safety. Performance Eliminator will remove over 99.95% of all oil smoke from discharge gas. Back pressure imposed on pump by smoke eliminator will range from 1/2 to 2 1/2 psi maximum at rated flow, depending upon amount of oil present in discharge gas. Range of back pressures to be expected at various percentages of maximum flow rates is shown in graph at right. Back pressure is established by degree of saturation of eliminator element which, in turn, depends on amount of oil smoke discharge by pump. This will vary with make, model, type and condition of pump... In-line models are suitable for systems with up to 10-psi operating pressure.

Construction
Eliminators are constructed of welded
steel and are finished with gray, baked,
oil and weather-resistant enamel. A
full hood provides protection against
the weather. The two-stage element is
made of inert material. End seals are
oil-resistant plastisol and prevent
leakage around the end of the element
... Replacement element kits are
available, although element service life
is extensive ... Units are easily
disassembled and re-assembled
without special tools ... Connection
sizes are available for a wide range of
applications.
Installation, servicing, and trouble-shooting instructions Accumulated oil must periodically be drained from the eliminator through the drain plug provided. Time interval will vary with each installation, but frequent inspection will easily establish a proper service schedule. If manual draining is required more frequently than appears to be practical, a commercial-type automatic trap can be connected to the drain, or the drain can be piped to an external sump. Where it is possible to connect |
the drain to a low pressure point in the
pump (to continuously return the
collected oil), provisions should be
made to limit the amount of air returned
with the oil. Eliminator element should be replaced if (1) a loss of performance efficiency is observed, or (2) back pressure has increased through the element, resulting in lengthy pump downtime or difficulty in maintaining required vacuum in system. When reassembling the eliminator following element replacement, be sure to tighten cover retainer nuts to prevent bypass of oil smoke around ends of the element. The following corrective action is recommended if, a) discharge smoke is observed emerging from under the cover of open-type eliminator modes. b) discharge smoke passes from the discharge outlet of in-line models. 1. Inspect element ... if a rupture or crack is evident, the element should be replace. (See Table on Page 4.) 2. If element appears relatively clean inside and out, and no ruptures or cracks are evident, inspect the end seals ... if they appear to be cracked or feel exceptionally hard, add a gasket of a soft commercial gasket material to each end. When reinstalling element, be sure it seals completely at each end to prevent smoke bypass. On in-line models, also be sure to tighten top cover plate against the gasket. |

How to order
First, select a model number based on
cfm capacity required (up to maximum
shown in Table on Page 4). Then add
proper code letters from table below to
indicate desired connection size and
type; example – Model VP20 with 2”
female pipe thread is VP20FL... To order
replacement element, select from Table
on Page 4 and be sure to include suffix;
example – Replacement element part
number for a Model V100 is 200256-8.
Sizing Select proper size by matching airflow capacity of the eliminator (see Table on Page 4) to the cfm capacity of the vacuum pump, or the sum of the capacities where more than one pump are manifolded into one discharge line. If imposed back pressure on pump is critical, derate to per cent of rated flow (shown in graph on Page 2) for maximum back pressure allowable. |
