Escort ELF Pump

 

Escort ELF air sampling pumps feature a state of the art electronic laminar flow sensor to provide a constant flow control with ± 2.5% regulation of flow rate (from 1-3 lpm) with automatic compensation for changes in battery voltage, temperature, altitude, and sample load. An internal secondary standard calibrates the pump continuously and needs to checked against a primary standard only once per month (or every 200 hours for coal mine dust sampling).

Features:

  • Patented electronic laminar flow control.
  • Internal secondary standard calibrates the pump continuously, maintaining OSHA compliance.
  • Check against a primary standard only once a month or every 200 hours for coal mine dust sampling.
  • Inlet filter traps moisture and particular matter.
  • Stainless steel-filled plastic case provides EMI/RFI protection.
  • Rated IP65 for resistance to water and dust ingress.
  • Exceptionally quiet operation.
  • Flow-Fault Indicator shows any sample inlet blockage.
  • Run/Hold feature allows “time out” during sampling process.
  • Elapsed time readout and low-battery warning.
  • Low flow and dual tube sampling available with Gemini Twin-Port Sampler.
  • 2 Year Warranty.

Approvals

 

  • NIOSH certified for coal mine dust sampling (TC-74-030)
  • MSHA certified as intrinsically safe for underground use (Approval # 2G-3924-1).
  • UL approved as intrinsically safe for use in hazardous locations, Class I, Groups A, B, C, D; Class II, Groups E, F and G; Class III, Division I locations.
  • ATEX Approved models available. Contact Zefon or your Zefon distributor for details

Specifications

 

Operating Flow Control : Volumetric flow rate held within ± 2.5% of set-point over the 1-to-3 lpm operating range (±5% to 0.5 lpm),
                                   with automatic compensation for battery voltage, altitude, temperature and sample load changes.

Flow Rate : Flow rate adjustable between 0.5 and 3 lpm; lower flow rates attainable (to 1 mlpm) with optional Gemini Twin-Port Sampling                              accessory.

Flow Indicat : Liquid Crystal Display provides 0.01 lpm resolution. Operating Range 30 inches of water load up to 2 lpm and 10 inches up to 3                           lpm.

Flow Blockage Detection : Flow-Fault LED comes on immediately when block is detected. Pump shuts down                                                                                               within 90 seconds if block is not cleared.

Elapsed Time Readout  : To 999 minutes in increments of 1 minute. Holds the last reading after either flow                                                                                             blockage or low battery shutdown and when pump is off or in hold mode. Operating Time Varies with flow rate and                                             sampling device loading.

Operating Temperature Limits : 32°-113°F (0°-45°C) Physical Weight 23 oz. (652 gm), with battery pack.

Dimensions : 2.25” D x 4.25” H x 4” W (5.7 cm x 10.8 cm x 10.2 cm), with battery pack.

Power Supply : 4.8-volt battery pack of four NiMH cells. (Units Mfg before Oct 2011 contain NiCd cells) 

Battery Pack Capacity : 2.8 amp hours (NiMH version), 2.4 amp hours (NiCD version) Battery Pack Recharge Time                                                                               14-16 hours (overnight) with Omega™ Charger.

Typical Battery Pack Life : 300 or more charging cycles
